Active Vibration Control Using Optimization Positive Position Feedback Based Genetic Algorithm By zhonghui wu
eBook (PDF): $0.00
Experimental, analytical and numerical analysis three kinds of methods are used for distributed parameter plate structure modeling, an infinite-dimensional and a very high-order plate mathematical... More > transfer function model is derived based on modal analysis and numerical analysis results. A feed-through truncated plate model which minimizing the effect of truncated modes on spatial low-frequency dynamics of the system by adding a spatial zero frequency term to the truncated model is provide. Active vibration control strategy is presented for a flexible plate structure with bonded three self-sensing magnetic transducers which guarantee unconditional stability of the closed-loop system similar as collocated control system. Both multi-mode SISO and MIMO control laws based upon positive position feedback is developed for plate structure vibration suppression.< Less
Positive Position Feedback Active Vibration for Plate Structure By zhonghui wu
eBook (PDF): $4.56
Active vibration control (AVC) methodology is presented by the author in this paper using bonded three self-sensing magnetic transducers for a flexible plate structure. Multi-modes... More > multi-input-multi-output (MIMO) positive position feedback (PPF) controller is tested and verified for vibration suppression through simulation and experiment implement. Based on genetic algorithm (GA) searching, optimal parameters of the controllers can be obtained according to the minimization criterion which is the solution to the H_∞ norm of the whole closed-loop system.< Less
