Gas temperature control of a high-temperature gas trial system

This paper introduces the function and the work principle of a high-temperature gas trial system (HTGTS), elaborates the importance of gas temperature control in the system, and provides the mathematical models of the system. According to the problems such as time delay, time-variant parameters, interference and so on exist in the control system of gas temperature; a cascade control strategy for the control of gas temperature is proposed. The simulation is carried out by using different control algorithms for the cascade control strategy of gas temperature. The simulation results show that the cascade control strategy named SDMC-LevfuzzyPID algorithm which proposed in this paper has better control performance than the traditional PID-PID algorithm.
