摘要：A servo control system having a proportional (P) or a proportional plus integral(PI) position controller, which output signal represents an input speed reference signalfor a speed close loop system with a speed controller detecting a speed deviation,derived from a speed feedback loop, which output signal represents an input current
reference signal for a current close loop system with a current controller detecting acurrent deviation, derived from a current feedback loop, which controls an amount of thecurrent flowing through a motor. The position controller detects the position deviationbetween a position reference signal and a position feedback signal separately for the Ppart controller, to produce a P part speed reference signal, and for the I part controller,to produce an I part speed reference signal, as a “two parallel-position outer loopfeedback control system” and includes a position reference reduction circuit with scalecoefficient less than one for the close loop with the P part controller. The P partcontroller and the I part controller connect to the summing unit, which sums the P partspeed reference signal and I part speed reference signal, and its an output signalrepresents the speed reference signal for the speed close loop system.
