SPEED CONTROL DEVICE FOR ELECTRIC MOTOR. |
摘要 |
<p>A speed control device for a motor having a speed feedback loop and a current feedback loop in which parallel capacitors (C1, C2) are connected to resistors (R4, R5) for specifying the limiting amplitude of an amplitude limiting circuit (33) when a speed deviation signal is used as a command signal for controlling a current through the amplitude limiting circuit (33) to limit the through rate dv/dt of the amplitude limiting circuit (33), thereby suppressing the occurrence of overshoot in the signal response characteristics and improving the stability in the transient response characteristics.</p> |
