Abstract
This paper presents a new control method for surge instability of the compressor system. Due
to the importance of the active control approach in improving the efficiency of the compressor
system, a new scheme based on the model predictive control (MPC) technique has been considered to control surge which gives the benefits of control signal optimization by considering
the constraints on states and input. Because of designing a novel MPC by using of linear matrix
inequality scheme, the optimization problem is solved in less time and with less complexity. The
proposed method is able to consider the limitation of the close coupled valve actuator and also
covers the uncertainty on the model. In addition, the developed model describes the nonlinear behaviour of the compressor system and handles the effects of the pipe on surge instability.
Using Lyapunov theory, the stability of the closed-loop system under the proposed robust active
controller is shown. The simulation results show the high pressure and high efficiency operation
of the system under study in different operating conditions.
