In Chapter 4, we not only give a new definition of fuzzy finite automata, of which the state transition accords with a compound fuzzy transition, but also present an important conclusion that the coarsest respecting compound fuzzy transition partition of states is same with the coarsest equivalent partition. In the discussion of coarsest partition, we give an algorithm respecting compound fuzzy transition which would be applied to get the coarsest respecting compound fuzzy transition partition.

So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.
