【Abstract】 Aiming at the problem of reducing efficiency of the actuator caused by traditional advanced angle compensation decoupling method,a new algorithm for the compensation of efficiency is proposed. The algorithm is based on the quantitative analysis of relationship between steering efficiency and projectile rotating speed,combined with characteristics of rotation control instruction of single channel rocket rudder system. This algorithm determines the phase compensation matrix and the efficiency compensation matrix at different frequencies. A simulation of this algorithm is carried out and the results show that the efficiency compensation decoupling method can effectively decoupling,and guarantee no reduction of the efficiency of steering gear at different rotating speeds and instruction frequency conditions.This method is easy to implement and is suitable for engineering application.更多还原
