Study on chemical reactor base on multi-model IMC-PID

Base on the database for mathematic model of chemical reactor, with base knowledge of internal model control is designed IMC-PID control system. Aiming at process of parameter variety with time -delay, a new IMC-PID control strategy based on multi-model is presented. The proposed multiple models are developed according to different work range and corresponding IMC-PID controller. With could overcome the influence caused by parameter variety. Computer simulation results show that the control strategy is effective and practical.
