Abstract :
A robust H∞ optimal design problem under a structure-specified controller is investigated for systems with parameter variations and disturbance uncertainties. A simple and facile design algorithm is proposed to solve the structure-specified H∞ optimization problem via genetic searching approach from suboptimal perspective. The proposed design method is very suitable for practical control systems. Therefore, the gap between the theoretical H∞ control and practical engineering designs can be filled up. Two examples involving a single input-single output (SISO) phase-locked-loop motor speed system with a lead/lag type controller and an MIMO supermaneuverable F18/HARV fighter aircraft system with a PID-type controller are given to illustrate the design procedure and exhibit the performance of the proposed method
