For solar thermal power generation system with fast time-varying, strong interference and uncertainty characteristics, combined with compensatory of the feedforward compensation to measurable disturbance, strong robustness of sliding mode control and the advantages of predictive control to handle obvious constraints effectively a method of feedforward sliding mode predictive controller is put forward to apply in solar thermal power generation heat collecting system. First of all, ignoring the heat loss in heat transfer process mathematical model of solar thermal power generation heat collecting system is established as prediction model of controller design. Progressive stable sliding surface was designed through the pole placement method, which effectively overcame the chattering phenomenon and reduced interference caused by uncertainty at the same time. Feedforward compensator was designed to compensate the effect of measured interference signal which is solar radiation to collector output. Simulation results show that feedforward sliding mode predictive control has strong anti-interference ability and improves the control accuracy compared with sliding mode predictive control.
