LQ Control Strategy Based on Frequency Multiplication Sampling and State Prediction

A new working method of networked control system is proposed to compensate the network-induced delay.Through the setting of buffers and application of frequency multiplication sampling,the delay can be obtained in real-time and the time lag in system loop can be farthest reduced.Based on the state prediction,the performance of networked control system could be improved greatly.The results show that the new method is practicable and effective.
