Nowadays the studies on flutter active control methods considering time delays have been focused on constant time delay in one control channel. However, the time delays in a control loop are maybe time-varying and exist in the forward channel, feedback channel or both. As a result, the control method that can compensate time delay influences was developed and used to realize the flutter control of uncertain time delay for two channels. The trick where "time-stamped" flag was added in the data transferred was proposed. The state predictor with the ability to compensate for the time delays in feedback channel was reconstructed to predict the controlled plant states. The predictive controller using state feedback in a state space form was designed to compensate the delays in the forward channel. Then the stability of the closed-loop control system was analyzed with the above mentioned control strategy. The airfoil with free-play nonlinearity was used in the simulation. Then the flutter active control schemes for controlled system with variable time delays in both forward and feedback channels were investigated. Finally, the effects of time delay size in different channels on flutter control were discussed. The simulation results show that the developed method can suppress the flutter effectively with different time delay in both channels and improve the system stability. From a control point of view, the time delay in the feedback channel may have more influence on the control result when the control method based on the system state feedback is used.
