PURPOSE:To improve the torque responsiveness of a synchronous motor by using the sum of adding a speed command and twice-differentiated speed command as a speed command of a control system, thereby compensating a torque generation delay in the system. CONSTITUTION:The trigger timing of a 3-phase inverter 3 is regulated by a speed controller 5. The controller 5 is composed of a voltage control oscillator 6, a sine wave generator 7, a hysteresis comparator 8, a gate logic 9, a current transformer 10, and a mixer 11. Here, a compensator 20 is added to twice- differentiate a speed command omega(t) and to multiply it by a constant K'. |
