Course Syllabus Course Aim: To represent various type of dynamic systems, including transfer functions, block diagrams, and state- space. Linear Control Systems aim to provide students with the ability to analyze closed loop system. Learn the purposes, advantages and disadvantages, terminology, and configurations of feedback control systems To develop a basic feel for the time-domain and frequency domain responses for simple systems. To give students knowledge and ability of determining the stability of a system for both the classical and modern control. To learn how to design a controller to meet time-domain specifications. These specifications include settling time, overshoot, steady state error, and maximum control effort. To provide the students an opportunity to apply the knowledge of above material in a practical (project) experience

Signals LTI System H(z) G(z) +

What is a System? System: Block box that takes input signal(s) and converts to output signal(s). Continuous-Time System: System InputOutput

What is a Control System A Process that needs to be controlled: –To achieve a desired output –By regulating inputs A Controller: a mechanism, circuit or algorithm –Provides required input –For a desired output Required Input Desired Output Process Output Controller

Closed Loop Control Closed-loop control takes account of actual output and compares this to desired output Measurement Desired Output + - Process Dynamics Controller/ Amplifier OutputInput Open-loop control is ‘blind’ to actual output

Model of Control System Environment Sensors ActuatorsSignal Capture Control Mechanical System Disturbances Noise Desired System Performance
