IPC: G10K11/178
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To secure the satisfactory convergence characteristic by updating the amplitude based on the equivalent transmission characteristic data corresponding to the angle frequency of every degree among those components of an adaptive coefficient vector when the fluctuation of the primary angle frequency of a periodic signal reaches its prescribed level. SOLUTION: The estimate ak corresponding to the primary angle frequency ωand the Gkp hat are read out of the equivalent transmission characteristic data 13 when the control is started and also when a frequency fluctuation decision means J1 decides that the fluctuation of the frequency ω of a periodic signal reached its prescribed level. These estimate hats are sent to the adaptive coefficient updating algorithm 11 via a path P1, and the amplitude ak and the convergence stable coefficient Gkp hat are updated among the adaptive coefficient vector W(n) components. Thus it is possible to perform the adaptive control at a speed higher than the convergence velocity that is secured by the single algorithm 11 even when the amplitude ak of the periodic signal differs according to the difference of frequency ω of the periodic signal.

When the motor 3 is abnormal, excessive current flows through the system and the resistor 4 and the driving circuit 2 generates more heat than under normal operating state. The heat detecting sensor 2b for the protective circuit detects the sum of heat generated in the driving circuit 2 and an adjacent resistor 4 and thereby the thermal protective circuit 2a functions thus stopping the operation of the motor drive circuit 2. According to the invention, time to be elapsed before thermal protection takes places can be shortened when overcurrent flows through the motor.
