线性多目标优化控制系统的设计

Design Method of the Linear Multi-objective Optimum Control

先讨论线性优化控制理论的缺陷,然后给出线性多目标优化控制系统的设计思想和方法,利用这个设计法,可以设计出一个受控系统,其不仅对阶跃响应,而且对匀速和匀加速响应都有快速平稳的品质指标,实现了线性系统的多目标优化。作为进一步拓展,再将该线性多目标优化控制系统加以非线性化,得到了更加优良的性能指标。

The defect of the traditional linear optimum control theory was discussed firstly. Then , a design method of multi-objective optimum control was presented. Appling the method to design a linear system, it can achieve a linear system with very satisfied performances not only for the step input signal, but also for uniform velocity and acceleration input signal. Finally, the linear multi-objective optimum control system was nonlinearized once again to get a nonlinearized system with more excellent performances for all the above-mentioned three input signals.
