The purpose of this paper is to present a universal controller system used in field oriented control method of ac machines. This controller system uses one Texas Instruments (TI(TM)) TMS320C14 digital signal processor (DSP), four analog-to-digital converters (ADC), three operation amplifiers, two current sensors and a resolver. The digital values of sine and cosine functions of the rotor position

Pulse Width Modulated (PWM) signal generation is crucial to many motor and motion control applications. PWM signals are pulse trains with fixed frequency and magnitude and variable pulse width. There is one pulse of fixed magnitude in every PWM period. However, the width of the pulses changes from period to period according to a modulating signal. This document discusses how to generate symmetric

The TMS320C16 evaluation module (EVM) is used to evaluate the performance characteristics of the TMS320C1x 16-bit fixed-point digital signal processor (DSP). This document builds a supplemental analog interface board that provides the analog capabilities commonly used by the DSP chip. This detailed document includes the schematics, the parts list, the cable connections, the power requirements, and

Due to its discrete nature DSPs represent variables and performs arithmetic functions with a finite word length. This produces three effects: the selection of filter transfer functions is quantized with filter poles and zeros existing only at specific locations in the z plane; the input is quantized; and noise is introduced from DSP multiplication and division operations. This document shows how
