The bestselling inspirational, upbeat collection of relatable lessons from the teen sensation, Mackenzie Ziegler—an award-winning dancer, singer/songwriter, and actress. Growing up is hard, but growing up in the spotlight is even harder. However, Mackenzie Ziegler is taking it all in stride, thanks to her positive attitude on life. From getting her start on Dance Moms, to her sold-out tour alongside Johnny Orlando, there’s nothing that she can’t do. In Kenzie’s Rules for Life, the dance prodigy, singer/songwriter, actress, and model offers her advice on friendship, family, fitness, style, and positivity. She shares lessons drawn from her own experiences for those navigating through their tween years on how to be happy, healthy, and confident in all aspects of their lives. The book also features a foreword by her sister Maddie Ziegler, author of the New York Times bestseller The Maddie Diaries.

This publication explains two rules related to the Ziegler-Nichols methods. The first method described is applicable if the controller tuning is done in a closed feedback control loop, while the second method can be utilized where an open loop step response is available or can be measured. Both tuning rules result in a closed control loop giving an overshooting response with a quarter wave decay of the oscillating control variable. Matlab examples are presented in order to simplify the reader's understanding of the given theory.

The vast majority of automatic controllers used to compensate industrial processes are of PI or PID type. This book comprehensively compiles, using a unified notation, tuning rules for these controllers proposed over the last seven decades (1935OCo2005). The tuning rules are carefully categorized and application information about each rule is given. The book discusses controller architecture and process modeling issues, as well as the performance and robustness of loops compensated with PI or PID controllers. This unique publication brings together in an easy-to-use format material previously published in a large number of papers and books. This wholly revised second edition extends the presentation of PI and PID controller tuning rules, for single variable processes with time delays, to include additional rules compiled since the first edition was published in 2003. Sample Chapter(s). Chapter 1: Introduction (17 KB). Contents: Controller Architecture; Tuning Rules for PI Controllers; Tuning Rules for PID Controllers; Performance and Robustness Issues in the Compensation of FOLPD Processes with PI and PID Controllers. Readership: Control engineering researchers in academia and industry with an interest in PID control and control engineering practitioners using PID controllers. The book also serves as a reference for postgraduate and undergraduate students."

Master process control hands on, through practical examples and MATLAB(R) simulations This is the first complete introduction to process control that fully integrates software tools--enabling professionals and students to master critical techniques hands on, through computer simulations based on the popular MATLAB environment. Process Control: Modeling, Design, and Simulation teaches the field's most important techniques, behaviors, and control problems through practical examples, supplemented by extensive exercises--with detailed derivations, relevant software files, and additional techniques available on a companion Web site. Coverage includes: Fundamentals of process control and instrumentation, including objectives, variables, and block diagrams Methodologies for developing dynamic models of chemical processes Dynamic behavior of linear systems: state space models, transfer function-based models, and more Feedback control; proportional, integral, and derivative (PID) controllers; and closed-loop stability analysis Frequency response analysis techniques for evaluating the robustness of control systems Improving control loop performance: internal model control (IMC), automatic tuning, gain scheduling, and enhancements to improve disturbance rejection Split-range, selective, and override strategies for switching among inputs or outputs Control loop interactions and multivariable controllers An introduction to model predictive control (MPC) Bequette walks step by step through the development of control instrumentation diagrams for an entire chemical process, reviewing common control strategies for individual unit operations, then discussing strategies for integrated systems. The book also includes 16 learning modules demonstrating how to use MATLAB and SIMULINK to solve several key control problems, ranging from robustness analyses to biochemical reactors, biomedical problems to multivariable control.

Bunheads meets The Kicks in this first novel in a brand-new middle grade trilogy from New York Times bestselling author, dancer, model, and actress Maddie Ziegler! Twelve-year-old Harper has been dancing practically since she could walk. She loves her dance studio and team, and just won her first ever top junior solo in a regional competition. But right before the school year starts, Harper’s parents drop a bombshell—the family has to relocate from their cozy town in Connecticut to sunny Florida for their jobs. That means goodbye to her friends, dance team, trips to see shows in NYC—and did she mention dance team? When she arrives at her new dance school and new team, it feels like everyone has better feet, quicker turns and faster taps than Harper. And it doesn’t help that a group of girls, who nicknamed themselves The Bunheads, wonder how the heck she made the team if she can’t even do a simple turn sequence in front of the class. Thankfully, Harper befriends Lily, a fellow newbie in the studio who is just as eager to make her mark and find a friendly face. With a big competition coming up for the dance team, Harper is determined to show everyone—especially those Bunheads—what she’s made of. And when a very badly timed injury threatens all of the work they have done, The Bunheads, Lily, and Harper must learn to truly work together to give them their best shot at the top spot!

The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory
