Semiactive Suspension

A Smith predictor-Taylor series-based LQG (STLQG) control to compensate time delay of a semiactive suspension system is newly presented. This control consists of a Taylor series-based LQG (TLQG) control and a Smith predictor based on the TLQG. The TLQG control compensates one half of time delay to decrease magnification from whole time delay compensation. The Smith predictor based on the TLQG compensates the other half to decrease horizontal shift from whole time delay compensation using the Smith predictor-based LQG. Finally, a practical case illustrates advantages of the STLQG control.

Time Delay Compensation

This paper studies the orbital pursuit-evasion problem with imperfect information, including measurement noise and input delay. The presence of imperfect information will degrade the players’ control performance and lead to mission failure. To solve this problem, a compensation control strategy for the players is proposed. The compensation control strategy consists of two parts: the guaranteed cost strategy and the time delay compensation method. First, a near-optimal feedback strategy called guaranteed cost strategy with perfect information is proposed based on a Lyapunov-like function and matrix analysis theory. Second, a time delay compensation method based on an uncertainty set is proposed to compensate for delayed information. The compensation control strategy is derived by combining the time delay compensation method with the guaranteed cost strategy. While applying this strategy to the game, the input of the strategy is generated by processing the measured data with the state estimation algorithm based on the unscented Kalman filter (UKF). The simulation results show that the proposed strategy can handle the orbital pursuit-evasion problem with imperfect information effectively.

Time Delay Compensation

Actuator is a key factor for vehicle active suspension. A new vehicle active suspension is put forward based on the Electro-Hydrostatic Actuator (EHA).For vehicle active suspension system, unavoidable time delay may appear in the controllable course. The critical time-delay of EHA active suspension is calculated in this paper and time-delay influence on the dynamic performance of vehicle active suspension is analyzed. A time-delay compensation strategy for EHA active suspension is proposed to reduce time delay. A self-adapting fuzzy controller is designed and applied to active suspension system with EHA. Physical prototype and experimental rig for EHA active suspension are built. Then time-delay tests of suspension prototype are carried out on the developed test rig. Test results show that the sprung mass acceleration of the active suspension with time-delay compensation significantly declines by 12.4% under the road input of 1.2Hz and by 13.6% under the road input of 1.6Hz.
