ARRANGEMENT FOR SPEED REGULATION OF ELECTRIC MOTOR

摘要

The controller for preventing imperfect combustion with a PID controller drives a blow motor at proper speed. Combustion state signal of output ports (B4-B7) determined by a microcomputer having reference rpm according to combustion mode is inverted by inverter (5) to apply to an adder (ADD1) which transmits error signal (EK) calculated from reference rpm signal and detected rpm signal by a counter (3). The error signal (EK) is feedbacked to the microcomputer through the PID controller.
