Facilities
Control Systems Lab, Digital Signal Processing Laboratory

Control System Toolbox™ provides algorithms and apps for systematically analysing, designing, and tuning linear control systems. The lab is well equipped with high-performance computers. Software packages such as MATLAB 2024 b with Simulink, which have a campus-wide license from Mathworks, and Code Composer Studio are installed on the systems. Students can specify the system as a transfer function, state-space, zero-pole-gain, or frequency-response model. Apps and functions, such as step response plot and Bode plot, let you analyse and visualise system behaviour in the time and frequency domains.

Students can tune compensator parameters using interactive techniques such as Bode loop shaping and the root locus method. The toolbox automatically tunes both SISO and MIMO compensators, including PID controllers. Compensators can include multiple tunable blocks spanning several feedback loops. Students can tune gain-scheduled controllers and specify multiple tuning objectives, such as reference tracking, disturbance rejection, and stability margins. Students can validate their design by verifying rise time, overshoot, settling time, gain and phase margins and other requirements.

Benefits to students:

  • Transfer-function, state-space, zero-pole-gain and frequency-response models of linear systems.
  • Step response, Nyquist plot and other time-domain and frequency-domain tools for analysing stability and performance.
  • Automatic tuning of PID, gain-scheduled, and arbitrary SISO and MIMO control systems.
  • Root locus, Bode diagrams, LQR, LQG, and other classical and state-space design techniques.
