| 摘 要： | 从参数估计与最优控制双目标优化的观点出发,采用大系统中分解-协调的方法,给出了一种对非线性系统四级递阶模型跟踪控制的算法,并用于求解带未知参数的同步电机励磁控制问题。仿真结果表明,此算法计算简便、结构分明,能达到较好的参数估计精度,而且能使非线性对象很好地跟踪模型。

| Abstract: | From the view point of the bicriterion optimization concerning parameter estimation and optimum control, a four-level hierarchical model following controller for a non-linear system is presented by means of decomposition-coordination technique of the large scale system. The algorithm is applied to solve a practical problem of controlling the excitation of the synchronous machine with unknown parameters. Simulation results show that the algorithm is easy in caculation and clear in structure. It not only makes the parameter estimation more accurate but also enables the non-linear plant response to follow that of the linear model quite closely. |
