Internal model control algorithm is used to control system analysis and design of multivariable reheat steam temperature system of domestic 200MW thermal power unit with steam heat exchanger. V standard control structure is adopted. In order to minimize the main channel delay, the compensated design of the controlled object is given. The controller design steps which can achieve decoupling without pure differential are given. The design of the filter array is described in detail. Purpose and process. Finally, the designed reheat steam temperature control system was simulated. The results show that the steam temperature control system has excellent control quality.
