Abstract: A couped dynamical feeded-supporting system for large radio telescope is investigated, where a coupled dynamical equation is proposed with hybrid finite element and Newton-Euler formulation for cable-cabin system and Stewart pl atform, then a new hybrid method is extended to solve the couped problem. And optimal control technique is used to decouple equation and obtain an optimal mass of moving Stewart platform with robust under some conditions. An numerical simul ation verifies the validity.
