Controlling apparatus of motor

Abstract

Abstract PURPOSE:To improve the lag time of the control response without reducing the cushioning action by giving the value that is obtained by adding a constant amount to a motorcurrent command value and a motor current to a cushioning circuit through a low priority excelling circuit. CONSTITUTION:An adder 8 adds the output DELTA I from a constant bias generating circuit 7 to the output of a currnt detector 5. In a low priority excelling circuit 6, the output IM3 of the adder 8 and the output IM0 of a motor current command unit 1 are compared to obtain the low priority excellence. The output IM2 of the low priority excelling circuit 6 is supplied to a cushioning circuit 2 having specified cushioning action, and the result of the subtraction between the output IM1 of the cushioning circuit 2 and the output of the current detector 5 is given to a chopper 3 as a command value. Thus, the lag time of the control response can be shortened.
