摘要
通过Matlab仿真,运用渐消记忆递推最小二乘法进行在线辨识,对溶解氧过程进行了广义预测控制的研究。通过尝试不同控制器参数,找到了控制效果较好的参数组合。同时对广义预测控制在快时变系统上的应用和相关参数的影响进行了探索。研究表明:广义预测控制比模糊自适应PID控制的电耗指标有所减少。
Through Matlab simulation and applying fading-memory recursive least-squares method to implement online identification,the generalized predictive control( GPC) of dissolved oxygen( DO) was investigated; and through testing of various controller parameters,the combination of parameters which boasting of better control effect was found. Investigating GPC's application in fast time-varying system and its influences on the parameters related show that GPC's power consumption index somewhat decreases as compared to the fuzzy PID control.
