Research of a Double PWM Governor System Using Frequency Conversion Based on DSP

The TMS320X240 is a member of the TMS320 family of digital signalprocessors (DSP), which is made by Dethou instruments. It has the architectural features necessary for high-speed signal processing and digital control functions, and it is coupled with the high-performance DSP core, its application enables the use of advanced control techniques for high-precision and high-effciency full variable-speed control of all motor types. This paper presents a new governor system using frequency conversion based on DSP. Its high performance allows real-time execution of very complex control algorithms and very high sampling rates to minimize loop delays. It proves that DSP will be applied extensively in future.
