摘要
伺服系统的性能与其控制器的设计有着密切的关联。针对永磁同步电机伺服系统,利用d-q坐标系下的数学模型,建立了永磁同步电机(PMSM)位置伺服系统的高阶传递函数模型。针对高阶系统传递函数特征根会出现不同解的情况,给出了基于极点配置的PID控制器参数确定方法。仿真实验对比讨论了不同参数选取对系统性能的影响,并给出了大致参数选取范围,在实际工程中具有一定的参考意义。
The performance of servo system has a close relationship with its controller design.In this paper,a high-order transfer function model of permanent magnet synchronous motor(PMSM)position servo system is established based on the mathematical model of d-q coordinate.As the characteristic roots of the transfer function have different solutions in the higher order system,this paper gives the method for parameters tuning of PID controller based on pole placement.Through the simulation experiments,we have discussed the influence of different parameters selection on system performance and given the approximate range of parameters selection.It has a certain reference value in practical engineering.
