This paper concerns the design problem of reliable Hinfin control for discrete-time systems with circular pole constraints. A reliable controller design method is developed. This method is based on Hinfin performance and multiobjective optimization in terms of LMI. A given Hinfin performance bound of the actuator failure cases is guaranteed and the performance in the normal case is optimized. Simulation...
Aiming at the difficulty of designing weighting matrices for linear quadratic regulator (LQR), a multi-objective evolution algorithm (MOEA) based approach is proposed. The LQR weighting matrices, state feedback control rate and optimal controller are obtained by means of establishing the multi-objective optimization model of LQR weighting matrices and applying MOEA to it, which makes control system...
This paper presents an algorithm for robust/spl Hscr//sub 2///spl Hscr//sub /spl infin// state-feedback control synthesis, with regional pole placement, based on a multiobjective optimization algorithm with non-smooth problem-solving capability. The problem is formulated with the state-feedback matrix coefficients as optimization parameters. The closed-loop performance obtained by means of the proposed...
