Ltd. Indiaa New Delhic2013,c2011 a562 aControl Engineering is the field in which control theory is applied to design systems to produce desirable outputs. It essays the role of an incubator of emerging technologies. It has very broad applications ranging from automobiles, aircrafts to home appliances, process plants, etc. This subject gains importance due to its multidisciplinary nature, and thus establishes itself as a core course among all engineering curricula. This textbook aims to develop knowledge and understanding of the principles of physical control system modeling, system design and analysis. Though the treatment of the subject is from a mechanical engineering point of view, this book covers the syllabus prescribed by various universities in India for aerospace, automobile, industrial, chemical, electrical and electronics engineering disciplines at undergraduate level. aContents 1 Introduction to Control Systems Learning Objectives 1.1 Control System Terminology 1.2 Basic Concepts of Control Systems 1.3 Requirements of a Control System 1.4 Types of Control System Summary Key Terms Objective-Type Questions Review Questions Answers 2 Mathematical Models Learning Objectives 2.1 Block Diagrams 2.2 Laplace Transforms 2.3 Transfer Function 2.4 Mechanical Systems 2.5 Electrical Systems 2.6 Electromechanical Systems 2.7 Stepper Motor 2.8 Analogous Circuit Systems 2.9 Thermal and Fluid Systems 2.10 Hydraulic Power System 2.11 Pneumatic System 2.12 Comparison of Hydraulic and Pneumatic Systems Key Terms Summary Objective-Type Questions Review Questions Numerical Problems Answers 3 Block Diagrams and Signal Flow Graphs Learning Objectives 3.1 Block Diagram of a Closed-Loop System 3.2 Block Diagram Simplification 3.3 Signal Flow Graphs Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers 4 Transient and Steady-State Response Analysis Learning Objectives 4.1 Test Signal 4.2 Static Response 4.3 Poles, Zeros and Stability 4.4 Transient Response Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers 5 Frequency Response Analysis using Nyquist Diagrams Learning Objectives 5.1 Frequency Response Analysis 5.2 Polar Plots 5.3 Stability Analysis using Nyquist Diagrams 5.4 Relative Stability, Gain Margin and Phase Margin 5.5 Frequency Domain Specification 5.6 M & N Circles 5.7 Nichols Chart Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers 6 Frequency Response Analysis using Bode Diagrams Learning Objectives 6.1 Bode Diagrams 6.2 Calculation of Transfer Function from Bode Plots Summary Key Terms Objective Type Questions Review Questions Numerical Problems Answers 7 Root Locus Plots Learning Objectives 7.1 Definition 7.2 Sketching Root Loci 7.3 Refining the Sketch 7.4 Effect of Adding Open-Loop Poles and Open-Loop Zeros 7.5 Advantages of Root Locus 7.6 Some Definitions Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers 8 Control Action and System Compensation Learning Objectives 8.1 Compensation 8.2 Types of Compensation 8.3 Compensating Networks 8.4 Design of Compensators Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers 9 Controllers Learning Objectives 9.1 Controller Principles 9.2 Two-Position Controller (ON/OFF Controller) 9.3 Proportional Controllers 9.4 Integral Controller 9.5 Derivative Controller 9.6 Composite Controller Modes 9.7 Selection of Controllers 9.8 PID Controller Tuning 9.9 Digital Controllers 9.10 Adaptive Controllers Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers 10 State Variable Models Learning Objectives 10.1 State Variables of Dynamic System 10.2 State Differential Equation using Physical Variables 10.3 Converting a Transfer Function into State Space using Phase Variables 10.4 Signal Flow Graph State Models 10.5 State Space Representation using Canonical Variables 10.6 Transfer Function from the State Equation 10.7 Eigen Values and Eigen Vectors 10.8 State Transition Matrix and Time Response 10.9 Controllability and Observability Summary Key Terms Objective-Type Questions Review Questions Numerical Problems Answers Appendix A Introduction to MATLAB Programming · A.1 Application of MATLAB Programs for Control Problems · A.2 Summary of Commands Appendix B Basics of Matrices · B.1 Definition of Matrices · B.2 Addition and Subtraction of Matrices · B.3 Multiplication of Matrices · B.4 Determinants · B.5 Transpose of Matrix · B.6 Adjoint (or Adjugate) of Matrix · B.7 Inverse of Matrix Model Question Paper 1 Model Question Paper 2 Model Question Paper 3 Bibliography Index aElectronics
