三角波曲线 meaning in Chinese

trangle

And classic pid control method and numerical pid control method have been introduced in the paper . the paper adopt stabilization border method to set the pid parameters and simulates the control system which is based on matlab / simulink . simulation results indicate that pid control ’ s simulation results have a good effect in low - frequency stage , but it is not perfect in mid - frequency and high - frequency stage
采用稳定边界法实现对pid参数的整定,并基于matlab / simulink对控制系统进行了仿真,仿真结果表明:低频段pid控制正弦跟踪曲线取得了良好的效果,而在中频和高频段时的跟踪效果不是很好, pid控制的阶跃响应超调量较大, pid控制三角波曲线的高频性能也不理想。
