IPC: H02P29/00
Filed: 1990-01-10
Abstract: PURPOSE:To arrest overshoot and chattering by performing variable manipula tion of input command setting according to the amount of deviation and limiting the deviation within a certain range of amounts. CONSTITUTION:The speed system of a motor 2 having a PI controller 1 has an input setting controller 3. The input setting controller 3 asserts deviation (e) between an input command N* and rotation frequency N as a quantity of state and produces final command input N** according to the condition of the deviation (e). If the amount of the deviation (e) exceeds the specified threshold alpha, the acceleration and deceleration is stopped with the unit addition quantity A of a ramp function zero. If the amount is equal to or less than the threshold alpha, output, which is the sum of an addition quantity beta as the thresh old made to be the unit addition quantity A and the present final command input N**, is obtained. Thereby the acceleration and deceleration can be regulat ed depending on whether the amount of the deviation (e) is larger or smaller than the threshold alpha.
