摘要： A device for controlling an induction motor includes a voltage/frequency controller, a pulse width modulation controller, and a converter. The voltage/frequency controller receives a controlling frequency, and outputs a controlling voltage corresponding to the controlling frequency. The pulse width modulation controller receives the controlling voltage and the controlling frequency, and generates PWM signals according to the controlling voltage and the controlling frequency. The converter receives the PWM signals, and controls the induction motor according to the PWM signals. There is a predetermined relationship between the controlling voltage and the controlling frequency stored in the voltage/frequency controller. The controlling voltage is greater than zero in response to the controlling frequency being zero, and increasing the controlling frequency increases the controlling voltage as in the predetermined relationship.

摘要： A pulse generator includes a pulse command register and a digital differential analyzer (DDA). The pulse command register includes a first register, a second register, and an adder. The first register receives and stores a pulse command from a CPU in an operating cycle. The second register receives and stores the pulse command shifted from the first register when the first register receives a second pulse command from the CPU in the operating cycle. The adder sums the pulse commands of the first register and the second register and the result is transmitted to the DDA. The DDA determines whether a pulse is to be generated after calculation according to the result from the adder of the pulse command register.

摘要： A speed controller used in a control loop of a motor includes a comparator, a processing device, and an arithmetic logical unit (ALU). The comparator compares a received instruction speed or a received measured speed of the motor with a predetermined speed value, outputs a first signal to the processing device when the received speed is greater than the predetermined speed value, or outputs a second signal to the processing device when the received speed is equal to or less than the predetermined speed value. The processing device receives a speed difference between the instruction speed and the measured speed. The processing device outputs a first proportional value when the first signal is received, or outputs a second proportional value when the second signal is received. The ALU outputs an instruction current to the control loop by calculating the proportional value according to a predetermined calculation rule.

The processor receives a speed, a moment of inertia, and a rotor position of the motor, to determine the cogging torque of the motor. Each band-pass filter is arranged with a different frequency to filter different frequencies of waveforms of the cogging torque. The processor determines a Fourier transformation of the cogging torque according to a number of Fourier coefficients from the band-pass filters, a cogging torque at a preset rotor position, and a cogging current according to the Fourier transformation of the cogging torque. The current control apparatus outputs a current opposite to the cogging current, to compensate the cogging torque of the motor.
