IPC: G05D3/12
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To shorten the time to be elapsed before settling at a target speed by making a switching from speed feedback control to position feedback control after the fluctuation of motor speed in constant speed region is settled within a predetermined level. SOLUTION: For example, a motor 6 is started based on a command being set at a start PWM set circuit 18 and speed feedback control is executed for a predetermined time in a constant speed region exceeding an acceleration region. Speed of the motor 6 is then operated over a predetermined continuous period of encoder pulse from an encoder 7 and compared with a reference speed to operate a speed error and a drive signal corresponding to the speed error is outputted from a drive means 5. Upon elapse of a predetermined time, position feedback control is executed in constant speed region. In other words, position of the motor 6 is operated by counting the encoder pulses and compared with a reference position to operate a positional error and a drive signal is outputted from the drive means 5 based on the positional error.
