Control method and control system for angle-controlled motor

The invention discloses a control method and a control system of a motor for controlling an angle. The rotating speed feed-forward type three-closed-loop servo motor control method is adopted, the precision and stability of angle control of a flow adjusting servo unit can be guaranteed through the three-closed-loop control method and control period setting, and therefore the stability of flow change is guaranteed; the closed-loop control with rotation speed feedforward can accelerate the response speed of the servo motor, and meets the real-time and high-responsiveness requirements of the system. In a further scheme, the segmented PID control method firstly ensures the index requirement of no overshoot of the flow regulation system, and further accelerates the response speed of the motor on the basis of ensuring no overshoot. 一种控制角度的电机的控制方法与控制系统。本发明采用转速前馈式三闭环伺服电机控制方法，其中三闭环的控制方法和控制周期设置能够保证流量调节伺服机组角度控制的精度和稳定性，从而保证流量变化的稳定；带转速前馈的闭环控制，能够加快伺服电机的响应速度，满足系统实时、高响应性。进一步的方案中，分段PID控制方法首先保证了流量调节系统无超调的指标要求，并在保证无超调的基础上，进一步加快
