通过对相平面分区控制的机理进行分析,为降低系统参数整定难度,提出了控制器的一种改进措施,引入两段相平面分区控制方法。其次,给出了控制力K0′的确定方法以及两段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。最后,通过高阶系统仿真示例,分析了两段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。

Analysis and simulation of Two-Step phase plane division control

Firstly,after a theoretical analysis of the phase plane divisional control,in order to tune the parameters,some methods were put forward,an improved controller was presented.Secondly,after the stability analysis of the high-order system,both methods were confirmed and the parameters adjusting principle of this controller were introduced.Finally,by several high-order simulation examples,the influence on the system performance of the first controller,the second controller and the acting time in this system was analyzed.The result of the simulation shows that both the dynamic and the steady properties are all taken into consideration and well dealt with in this method,which possesses a comparatively better performance of anti-disturbance.
