摘要：
In the fields of energy, chemical industry and mechanical manufacturing, temperature control is closely related to important technical indicators such as product quality, production efficiency and energy consumption. Aiming at the problems of large inertia, large lag and nonlinearity in current thermal inertia systems, in this paper, a temperature control method based on optimal control is proposed. The temperature optimal control is combined with closed-loop PID control and the undisturbed switching technology is applied to the system. In the system, precise temperature control is performed on the controlled object. The experimental results show that the control method proposed in this paper has shorter control time, less overshoot and stronger anti-interference ability than PID control.
