Unformatted text preview: diagram above to the Note diagram in the previous slide! 15 Control system design objective To design a controller s.t. the output follows the reference in a “satisfactory” manner even in the face of disturbances. 16 Goals of this course Systematic controller design process Disturbance Reference Controller Actuator To learn basics of feedback control systems Output Input Plant Sensor 4. Implemenation 1. Modeling Controller Mathematical model 3. Design 2. Analysis Modeling as a transfer function and a block diagram Modeling • Laplace transform (Mathematics!) • Mechanical, electrical, electromechanical systems Analysis Analysis • Step response, frequency response • Stability: Routh-Hurwitz criterion, (Nyquist criterion) Routh(Nyquist Design Design • Root locus technique, frequency response technique, PID control, lead/lag compensator Theory, (simulation with Matlab), practice in laboratories Theory, Matlab), 17 18 Course roadmap Modeling Analysis Laplace transform Transfer function Models for systems • mechanical • electrical • electromechanical Linearization Time response • Transient • Steady state Frequency response • Bode plot Stability • Routh-Hurwitz Routh• (Nyquist) Nyquist) Summary & Exercises Design Introduction Introduction Examples of control systems Examples Open loop and closed loop (feedback) control Open Automatic control is a lot of fun!
