Abstract :
To improve the control performance of existing control loop, a weighted double loop control structure (WDLCS) is proposed for processes with time delay. The output feedback absolute error (OFAE) is defined to introduce the WDLCS´s performance of reducing the effect of delay and parameters time-varying. Then the selection strategy of the weighting factors is given. Simulation results show the effect of improving the original structure performance.
