Generally, it is hard to realize constantvelocitycontrol by means of closed-loop control based on motor steady equivalent equation.
一般基于电机稳态等效方程的闭环控制很难实现恒线速运行控制。
2
Control of the actuator velocity and if necessary maintaining it constant with varying loads.
执行器速度的控制,如果必要维持其在变化负载下的稳定。
3
Then a vector control method with speed closed-loop and magnetic linkage closed loops put forward, which is based on the constantvelocity by means of stator flux-oriented vector control.
