| description | PROBLEM TO BE SOLVED: To provide a motor controller which can simplify a constitution in the case of controlling and regulating a current, which instantaneously decides an optimum current control proportional gain or an integrating gain when a motor parameter changes and which can stably respond to the current. SOLUTION: A current control system supplies power to a permanent magnet type synchronous motor 1 from a battery 4 through an inverter 2. The control system comprises, for example, a proportional gain table for presetting the proportional gain in response to a d-q-axis current command value as a table, an integrating gain table for presetting an integrating gain in response to a winding temperature as a table, and a gain regulating means for retrieving a set value of the proportional gain of PC control by the proportional gain table or the integrating gain table when the current control gain is set by applying the PI control, in a current control arithmetic unit 20. |
