Abstract

This paper investigates the reliable tracking problem against helicopter actuator impairment under different trimming points with parameters uncertainty. First, the model of actuator faults is presented. Then a reliable robust tracking controller design methodology is developed. The algorithm is based on the iterative linear matrix inequalities (ILMIs), which has less conservativeness than the standard LMI method. The effectiveness is demonstrated by a numerical example of a helicopter model and its simulation results.
