But in fact, the system of half-tracked air-cushion vehicle is over complicated. When the vehicle drives in an unknown soil, the parameters and structures of controlled member will change with load or disturbances. This system is nonlinear and time-variant, and it is very difficult to analyze its transfer function and state function quantitatively.

然而在实际工作中，由于本课题中的系统过于复杂，当行驶在未知土壤条件下时，被控对象往往随着载荷或干扰因素影响，其特性参数或结构发生改变，属于非线性和时变性的不确定系统，它的传递函数或状态方程难于用传统的定量分析方法加以实现。

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.
