This paper discussed the time-delay filtration technique, and analyzed the importance of precise design of the parameters of time-delay filter, also a proposal was bring forward about an adaptive time-delay filtration control structure based on genetic algorithm toolbox (GAOT). Furthermore, the control block diagram was given, then optimized the three parameters of the time-delay filter based on GAOT...
Internal model control (IMC) has been widely used because of its easily designed method and simple tuning policy. But better performance cannot be obtained when it is used in hydraulic servo system control directly because of the systemspsila uncertainties, time varying and highly nonlinear characteristics due to the flow-pressure relationship, oil leakage, oil temperature variation, load disturbances,...
