本文研究了一类非线性系统的广义预测控制，将其等效为时变线性系统，然后在线辨识时变参数，进行广义预测控制。给出了两种辨识时变参数的方法，并以二容液位系统为模型，进行了仿真研究，结果表明，此方法计算量小，工作点变化时跟踪速度快，具有较好的控制效果。

A Generalized Predictive Control for a class of nonlinear system is studied in this paper. First the nonlinear system is substituted with a time varying linear system and then the time varying coefficients are identified on-line. Two identify methodsare proposed and used to simulate the two-tank level system. The simulation results -demonstrate that lower calculation, fast tracking speed, and good control effect of the nonlinear system are obtained.
