Virtual Axis Machine Motor Servo Control System Parameters Tuning Method

虚拟轴机床电机伺服控制系统的参数整定是虚拟轴机床设计的重要基础部分,论文对位置环控制器PID控制的参数和速度环控制器PID控制的参数使用遗传算法优化整定,并把优化整定结果和常规Ziegler-Nichols方法做了分析比较,同时对若干控制器的参数使用遗传算法同步实施优化整定,获得了非常好的结果。最后,在虚拟轴机床运动学控制的数学模型中添加了上述优化整定后的参数,进行仿真实验研究,仿真实验结果表明,对虚拟轴机床电机伺服控制系统的参数使用遗传算法优化整定,不仅优化的速度较快,而且可以获得令人满意的优化结果。

Virtual axis machine tool motor servo control system of parameters of the whole set for the vir- tual axis machine tool design the important basis for part of this article on the position of the ring control- ler PID control parameters as well as the speed ring controller PID control parameters using the genetic al- gorithm to optimize tuning, and the optimization of the whole setresults and conventional Ziegler-Nichols method are analyzed and compared to the same time, the number of controller parameters using genetic algorithm implemented simultaneously optimized tuning, and get very good results, and finally, in the mathematical model of the virtual axis machine tool kinematics controladded to the above optimization tuning parameters, and the simulation experimental research. Simulation results show that the virtual axis machine motor servo control system parameters using genetic algorithms to optimize tuning, not only to optimize speed, and can obtain satisfactory optimization results.
