Abstract

PURPOSE:To eliminate the control lag resulting from the computing time for the subject control system by a method wherein the armature current value in a certain time zone is estimated from the armature current value in the preceding time zone, and an igniting phase angle is determined based on the estimated value. CONSTITUTION:The armature current value, armature voltage value, speed value and the like are inputted to a multiplexer 119 together with the output of a speed command signal generator 117, and when the igniting phase angle of a three-phase inverted parallel inverter 114 is controlled by performing an arithmetic operation, the armature current value IES (N) in a time zone Tn is estimated from armature current sample value Ia(N-1) and Ia(N-2) in a time zone Tn-1 and Tn-2, using the formula of Ies(N)=Ia(N-1)+G1.[Ia(N-1)-Ia(N-2)]. And using this estimated value Ies(N) as an armature current value, an arithmetic operation is performed and an igniting phase angle of the inverter 114 is determined.
