| Abstract: | This paper presents the distributed control system structure of cabin and its realization. Double mode control strategy of P PID in cable system is proposed too. Optimal results of PID are obtained by means of combination of stable limits tuning method and simplex search method. Then authors discuss the constitution of GPS real time determination system for the location and attitude of the cabin. The transfer matrixes of cabin's location and attitude are deduced, and the equations to solve the location and attitude of the cabin are gained . With the help of GPS real time determination system, cabin system will be a closed loop control system. |
