GATE Control Systems: Compensators and PID Controller – Previous Year Questions

5 GATE previous year questions on Compensators and PID Controller (Control Systems, Electronics and Communication Engineering) with answers and explanations, from every paper.

  1. GATE 2017 EC Q30 (1 mark, Multiple choice) – Which of the following can be the pole-zero configuration of a phase-lag controller (lag compensator)?
  2. GATE 2015 EC Q57 (2 marks, Numerical answer) – A lead compensator network includes a parallel combination of R and C in the feed-forward path. If the transfer function of the compensator is G c(s)…
  3. GATE 2024 EC Q38 (2 marks, Multiple choice) – A satellite attitude control system, as shown below, has a plant with transfer function G(s)=1s2 cascaded with a compensator C(s)=K(s+)s+4, where K…
  4. GATE 2025 EC Q36 (2 marks, Multiple choice) – Let G(s)=110s2 be the transfer function of a second-order system. A controller M(s) is connected to the system G(s) in the configuration shown below.…
  5. GATE 2026 EC Q40 (2 marks, Multiple choice) – For the control system shown in the Figure, the transfer function of a plant, G(s)=1(s+1)(s+2) is connected in cascade with a compensator C(s)=K(s+),…
