High accuracy speed measurement for rotary motor based on DSP

Measurement of the motor speed has great influence on the control effect of effectiveness and precision of motor control. Conventional methods such as M method, T method, M/T method cannot satisfy the demand of the velocity measurement error in the operating range of the motor. A new method for speed measurement based on Digital signal processor TMS320x28xxx is presented; the experiments show that the new method can meet the accuracy requirements in the operating range of the motor.
