A three element PID controller is currently widely used to control the drum level of power plants. The authors’ experience with this compensation technique showed the existence of large overshoot in the system response and the difficulties in tuning the PID parameters. Any attempts to reduce the overshoot leads to unacceptable slow response.

The purpose of this paper is to use a robust multivariable loop shaping design technique to improve the control of the drum level of the plant. Simulation results show great improvement in the compensated system response in addition to its robustness to plant parameter variations.
