Digital Speed Governor System Based on TMS320F28335 Chip for a Gas Engine

This paper presents a digital speed governor system for a gas engine based on TMS320F28335. In speed governor system, hall sensor A04E is used to measure speed; L298N is used to drive the step motor; torque vector control is used to subdivise the angular of step motor. Fuzzy control and PID control are used together, fuzzy control implement fast control, PID control implement accurate control. Fuzzy PID control improves dynamic response while the load change, and keep the governor performing well in a wide operating range.
