Study of Internal Model Control Based on Feedforward Compensation

For the common time-delay problems in the industrial process control, combined with controlling superiority and a good tracking performance in feedforward control of internal model control(IMC) on the time-delay system, a method based on feedforward compensation is brought up. In this paper, for the glass tank furnace charged with variable time lag, as well as the input variables vulnerable to interference, we use the method to carry out the analysis, the results show that the method has a good track and disturbance rejection performance in time-delay system.
