A Multimode Controller Design for a TBM Autopilot with Optimal/Classical Approach

Abstract

This paper introduces design of a multimode controller for a Tactical Ballistic Missile autopilot that combined optimal control method with classical frequency domain analysis. In the paper, optimal control method is used to system structure design and to determine gain coefficient, frequency constraints in classical control theory are used to limit the weighting coefficient matrix of objective function in order to ensure system robustness. The simulation results show that the corresponding system responses have better quickness and some robustness, but the overshoot becomes a bit larger with contrast to traditional method.
