PURPOSE:To stabilize a control system by automatically correcting the proportional gain of a speed regulator via an automatic tuning circuit to control a current. CONSTITUTION:An automatic tuning circuit A is composed of differentiating filters 5, 6, a multiplier 7, a switch 8, an integrating element 9, a comparator 10, dividers 11, 12, an inverting amplifier AMP, and a switch S1. This circuit A calculates the DC motor field magnetic flux and the motor starting time constant on the basis of the actual motor speed value and the actual motor current, and controls the output of the regulator 1 on the basis of the calculated result. In other words, the circuit A automatically corrects the proportional gain of the regulator 1 to control the current and enhances the stability of the control system. |
