【摘要】 研究了有约束无模型控制问题,首先对一般的MISO无模型控制(NMC)给出了一个简单合理的收敛性条件。由于实际应用中完全无约束的控制系统并不存在,为此考虑输入输出有上下界约束的无模型控制问题(NMCC)。通过无模型控制方法中的泛模型,将对输出的约束转化为对输入的约束,进一步分析了有约束无模型控制问题的可行条件,并在不可行时给出了对软约束的调整方法,进而得出求解这种约束问题的一般算法。最后给出了一个仿真算例说明了方法的有效性,并在一定条件下给出了约束问题的收敛性证明。更多还原

【Abstract】 A simple and reasonable convergence condition is given for general MISO non-modelling control(NMC) problems.For there is no control system without any constraint,it is necessary to discuss non-modelling control problems with constraints(NMCC).The output constraints are transferred into input constraints by the universal model of non-modelling control method.The feasible conditions of NMCC problems are analyzed,and the adjusting methods are considered when NMCC problems are infeasible.A general algorithm of NMCC problems is given,and its convergency is proved to certain conditions.A simulation example shows that the algorithm is available.更多还原
