Abstract

PURPOSE:To make an impact drop of the speed small and the recovery time short in a sudden load change by adding an estimated value of a load torque disturbance and the differential value to a speed regulator output signal. CONSTITUTION:A state observer 2 consisting of a constant equivalvent model 8 in a start of a motor, a multiplier 9, amplifiers 10, 11, an integrator 12, a base speed setting device 15, dividers 13, 14 and a blind sector operational element 16 has outputs of a current actual value ia and a speed actual value n and adds an estimated value of a load torque disturbance and the differential value to an output signal of a speed regulator 3. By doing so, an output of the speed regulator 3 hardly moves at the neighborhood of zero, and a forecasting control is done in a sudden load change by a compensating signal from the state observer 2 to make an impace drop of the speed small and the recovery time short.
