模糊理论结合PID控制方法在集中供热系统中的应用

集中供热系统是一个具有大惯性、纯滞后特点的复杂非线性系统，为了提高系统稳定性，实现合理用热，将模糊自适应控制和常规PID控制两种控制方法结合并使用模糊工具箱进行了系统仿真实验。实际结果表明，同常规的PID控制方法相比，模糊自适应PID控制方法有效提高了集中供热系统的鲁棒性、稳定性和自适应的能力。在集中供热的复杂系统中，能更好的满足用户的热需求

The application of fuzzy adaptive PID controller in central heating system

Central heating system is a complex nonlinear system with large inertia and pure delay. In order to improve system stability and realize reasonable heat consumption, the fuzzy adaptive control is combined with the conventional PID control, and the system simulation experiments is carried out with the fuzzy toolbox. The results show that the fuzzy adaptive PID controller effectively improves the robustness, stability and adaptive ability of the central heating system, compared with the conventional PID controller. It can better meet the thermal needs of users in the complex system of central heating.
