A Co-Optimization Method of Actuators/Sensors Placement and LQG Controller for Vibration Suppression

In the manufacturing industry, high acceleration demands lead to lightweight designs of stages, while it may cause undesirable vibrations. order obtain most efficient vibration suppression performance, this paper proposes a co-optimization method realize simultaneous optimization Actuators and Sensors (AS) placement controller parameters. The includes an inner cycle for minimizing control energy by Linear Quadratic Gaussian (LQG) controller, outer optimizing closed-loop 1-norm is constructed as criteria cycle. Besides, Dynamic Opposite Learning Enhanced Teaching–Learning-Based Optimization (DOLTLBO) algorithm applied enhance searching ability. Numerical experiments on stage were performed validate method. results reveal that new has strong ability in AS parameters, can finally guarantee superior performances suppression.
