Analysis On Compensation and Effects of Time Delay In Vibration Control

In the view of this practical problem, the paper has carried on research to the active control algorithm with time delay compensation, started with the single-degree-of-freedom system, the maximum allowed time delay were investigated. Adopted optimal control algorithm, and phase compensation was used to compensate time delay. Simulation results indicate that time delay may be effectively compensated by phase compensation, the presented time delay compensation control algorithm is effective in reducing the maximum response of the systems and the system stability can be guaranteed.
