摘要
针对直流电动机调速系统的非线性和结构参数易变等特点,利用一种新型的控制器——九点控制器,对双闭环调速系统的转速环进行控制;为了验证控制效果,分别对直流电动机的参数变化、负载突变等情况进行仿真研究,并与常规PI控制进行比较.结果表明,九点控制器在电机参数变化以及负载突变时都有较好的控制性能.
According to the characteristics of nonlinear and structural parameters varying easily of the direct current (DC) motor, A new-type controller named ninepoint controller is used to control the rotate loop of the double closed loop speed regulation system.In order to validate its control effect, the simulations of the DC motor in the case of the parameters variety and the load changing suddenly are made respectively.And then it is compared with the traditional PI control.Simulation experimental results proved that the nine-point control has good performance under the above-mentioned circumstances.
