Simulation study on setting of PID controller parameters according to critical proportioning method

PID控制器参数的整定是PID控制系统设计的核心。为了整定PID控制器参数,基于Matlab/Simulink仿真环境,采用临界比例度法整定PID控制器参数,通过仿真实例很好地实现了对PID控制器参数的整定。该仿真具有直接观察系统性能变化,快速、准确选择合适PID参数,充分体现了Matlab/Simulink直观、方便的特点。

The setting of PID controller parameters is the core of PID control system design.The critical proportioning method was adopted to set the PID controller parameters under the condition of the Matlab/Simulink simulation.The parameter setting of PID controller was implemented by a simulation example.The innovation points for this paper is that the simulation has the features of observing the variation of the system performance,and selecting appropriate PID parameters quickly and accurately.It also fully reflects the intuitive and convenient characteristics of Matlab/Simulink.
