A BANK-TO-TURN MISSILE AUTOPILOT DESIGN APPROACH USING LQR CONTROL THEORY WITH FREQUENCY DOMAIN CONSTRAINT CONDITIONS

本文研究了线性二次型最优控制系统的加权阵与频域指标间的对应关系，基于回路成形理论给出了加权阵选择方法，并将其应用于ＢＴＴ导弹的自动驾驶仪设计。在建立了无静差控制模型的基础上，获得了满足预定频域指标的设计结果，并通过自动驾驶仪系统的非线性仿真验证了设计方法的有效性。

In this paper, we discussed a correlation of the frequency domain performance and the weighting matrices for linear quadratic optimal control system. Based on the loop shaping theory, a method determining weighting matrices is given, and it is used to design a bank-to-turn (BTT) missile autopilot. Based on the zero steady state error control model,design results to satisfy frequency domain performance requirements are obtained,and the effectiveness of this method is verified by nonlinear simulation of a certain autopilot system.
