Application of Self-Tuning Control 900593

Two kinds of self-tuning control algorithms have been applied using a novel smoke sensor as part of a diesel smoke control system. Firstly, pole assignment self-tuning control was used to achieve the desired engine speed response, with a smoke predictor used to solve the problems caused by the time delay between the fuel input and smoke output; secondly, a Pl self-tuning controller was used to solve the problem caused by the variation of the coefficients in the transfer functions with engine conditions. The experimental results and the problems and the ideas for future work are discussed.
