英文摘要：

As the characteristics of online computational complexity of supervisory predictive control,and the stair-like control strategy is introduced,which reduced the online computation,and the computation time. Improvement on the algorithm based on stair-like supervisory predictive control,predicted output error is introduced in the objective function to suppress output overshoot. IGCC gasifier temperature control is adopted for the simulation. Simulation results show that the use of non-quadratic performance indexes of stair-like supervisory predictive control algorithm can also achieve good control effect,adjust the system to meet the stability,accuracy and immunity requirements.
