Abstract

To solve rationality problem using low order feedback to control high order system, a method of system decomposing based on closed-loop time scale characteristic was used. The influence of performance index weights on sixth order roll autopilot system characteristic was analyzed. The differences of feedback state choosing between second order, fourth order and current system reduced order were discussed, and the performances were simulated and compared respectively. The results show that: Only if the feedback states contain all slow modes through design of performance index weights, the reduced control can achieve the performance requirement.

Key words： two-scale system; LQR design; reduced control; weights
