Welcome to ME2142E/TME2142 Feedback Control Systems...
Students are able to obtain dynamic models of simple physical systems, particularly mechanical and electrical systems, and obtain the transfer functions of these systems.
Students are able to determine the transient response of first and second order systems.
Students are able to determine the stability characteristics of a system using Routh’s stability criterion and the root locus method.
Students are able to determine the steady state error characteristics of systems.
Students are able to determine the steady state frequency response of physical systems and represent the frequency response graphically in terms of Bode and Nyquist plots.
Students are able to determine the stability of physical systems through the frequency response using the Nyquist stability criterion.
Students are able to determine the relative stability measures such as gain and phase margins and to translate these values in terms of transient response.
Students are able to conduct simple experiments determining performance of control systems
