摘要
通过对相平面分区控制方式的分析,为扩大控制器适用范围和降低系统参数整定难度,提出了控制器的一种改进措施,引入分段相平面分区控制方法。采用了控制力的确定方法以及改进相平面分区控制器参数整定原则,并对系统稳定性进行了分析。通过高阶系统仿真示例,分析了改进相平面分区控制系统中的第一控制器参数、第二控制器参数、作用时间这三类控制参数对系统性能的影响。仿真结果表明,该方法能较好的兼顾系统的动态、稳态特性,并具有较好的抗干扰能力。
Firstly, after a theoretical analysis of the phase plane divisional control, for extending the application area and easily tuning the parameters, an improved controller was presented. Secondly, after the stability analysis of the high -order system, both the method of confirming K＇o and the parameters adjusting principle of this controller were introduced. Finally, with several high -order simulation examples, the influences of the first eontroller, the second controller and the acting time in this system on the system performance were analyzed. The result of the simulation shows that both the dynamic and steady properties are all taken into consideration and well dealt with in this method, which possesses a comparatively better performance of anti - disturbance.
