Long time delay is a very common phenomenon encountered in process industry and it is difficult to control by conventional methods. To solve this problem, a decentralized predictive control method is presented. According to the structure of the process industry with long time-delay, it can be decomposed into a series of short dead-time problems. In order to further overcome the effect of dead-time, generalized predictive control strategies are used for short dead-time problems. A simulation example is given to illustrate the effectiveness.
