    Control Systems

    Topics include mathematical modeling of control elements and systems, performance analysis, stability assessment and system compensation. Both time domain and frequency domain techniques are used. Multi-variable processes are discussed using state space models. Discussion extends to the basic concepts of controller design, root locus method and frequency response method. Controller design methods specific to phase lead/lang compensator and PID controller are presented. MatLab control tools are used in computer simulation and in various analyses of control systems.
