由于实际系统中通常存在约束,如何保证预测控制集结策略在有约束系统中的控制质量,对于集结策略的实际应用有着重要意义。这里通过对预测控制拟等效集结策略进行仿真分析,提出了一种确定拟等效集结策略中参数取值的算法.应用该算法,可以使基于拟等效集结的预测控制器对于有约束系统在降低在线计算量的同时保证系统的控制质量,进而达到近似等效的目的。
Constraints always exist in many practical control systems. How to guarantee the control quality is very important for the aggregation based Model Predictive Control (MPC). Through analyzing the quasi-equivalent aggregation strategy of MPC on the basis of the simulations, an algorithm was proposed to determine the parameters of quasi-equivalent aggregation strategy. By this algorithm, for the quasi-equivalent aggregation based MPC, the on-line computation complexity could be reduced as well as the control quality was guaranteed.
