Research of Aero-Engine Robust Fault-Tolerant Control Based on Linear Matrix Inequality Approach

摘要

Associated with the problem of fault tolerant control against actuator fault happened to the aero-engine, a D-stabilized robust tolerant control approach was proposed based on linear matrix inequality (LMI). To satisfy the regional poles constraints and performance in actuator fault condition and structured perturbations, a state feedback fault tolerant controller was designed in terms of feasible solutions to the LMIs. Simulation results illustrate that, the proposed approach can maintain the performance of robust stability in specified pole region as well as integrity of the control system in actuator fault condition, with allowable perturbations and fault bounds.
