Xu, C. and Xu, H., 2020. Self-tuning method of electronic governor parameters for marine medium-speed diesel engine. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 378–381. Coconut Creek (Florida), ISSN 0749-0208.In view of the importance of electronic governor in marine diesel engine and the poor stability and fault-tolerance of the research results on parameter self-tuning, a self-tuning method of electronic governor parameter for marine medium-speed diesel engine based on fuzzy PID is proposed. Based on the electronic governor control system of diesel engine, the self-tuning environment of electronic governor parameters is built by using real actuator and rapid control prototype hardware, and the self-tuning scheme of electronic governor parameters is studied. Considering the non-linearity and time-varying characteristics of diesel engine, the self-tuning of electronic governor parameters is realized by using adaptive fuzzy PID control technology and variable universe idea. The experimental results show that the proposed method can effectively enhance the fault-tolerance in the process of parameter self-tuning by means of fuzzy control. Its stability is superior to the reference results, and it has reliability.
