Generalized predictive control applied in waste heat recovery power plants

A multivariable control strategy is needed to ensure high efficiency and load-following capability in the operation of waste heat recovery power plants. In this paper, a generalized predictive controller is proposed for a waste heat recovery process operating on an organic Rankine cycle. The simulation results show that the proposed control strategy not only can achieve good transient and steady response along with decoupling performance, but also can obtain satisfactory disturbance rejection performance.
