CONTROLLER FOR ELECTRIC AUTOMOBILE

摘要

PURPOSE:To improve the accelerating performance at the accelerating time by applying correction of an armature current which decreases in response to the variation in the rotating speed of an engine at the current instruction value at the accelerating time. CONSTITUTION:An armature current instruction generator 10 outputs a current instruction Imc in response to an acceleration signal ACC, and a DELTANm detecting and instructing correction value calculator 12 outputs a correcting instruction value ImD=DELTANmXKN (DELTANm: variation in the motor speed, KN: correcting gain). An adder 122 adds the current instruction ImC and the value ImD and calculates the corrected instruction value ImO. A butting circuit 84 calculates the deviation between the value ImO and the signal Imff which is averaged value of armature currents imf, and applies a current flow rate alpham through a compensator 81 and a current flow rate control oscillator 82. In this manner, the accelerating performance can be improved at the accelerating time without defecting the stability of a current control system.
