控制信号

Based on accurate step motor system parameters, the state equations describing step motor dynamic characteristics are set up. The operation of the self synchronization closed loop control system is simulated on computer. In the research the principle analysis and system design have been done about self synchronization closed loop operation. The relation between rotating EMF and the rotor position of the step motor is discussed. Through detecting the zero value of rotating EMF the rotor position of the step motor is indirectly obtained.
