This course introduces the basic priciples of feedback control of dynamic system, related system analysis technics, and the design of the controller satisfying the given dynamic specifications. To achieve the course goals, system odeling technics descrbing the dynamic systems into mathematical differential equations, technics (root locus, Nyquist) analyzing the dynamic characteristics (stability, tranqusient response) in both time and frequency domain ill be studied. Also, PID and lead-lag controller design method that makes the system dynamic characteristics satisfy the required specifications will be investigated.
