The authors propose a new design and realization method solving for constrained multi-objective problem via an advanced evolution strategy. Requirements directly related to the H and H2 performance specifications are imposed, which reflect stability robustness and optimality. A modified PID control scheme represented only by two parameters is proposed to control a linear brushless DC motor. The design paradigm offers an effective way to implement robust solutions that covers a wide range of plant perturbations and offers excellent performance. Simulation studies and experiments are performed to verify the performance and applicability of the suggested design.
