温控系统采用的PID控制时，控制参数无法适应系统时变性要求，从而影响控制效果。模糊控制具有不依赖模型及对干扰和参数变化不敏感特点，提出了一种利用模糊策略在线优化 PID 参数的方法。仿真并实验测量表明，在调节时间、超调量和静差等方面都有较佳的表现。

In the temperature control system adopting PID,control parameters cannot meet thetime-varying requirements of the system,thus affecting its control effect.Considering fuzzy control is characterized by independence from the model and insensitivity to interference and parameter variations,this paper proposes a fuzzy strategy to achieve online optimization of PID parameters.Simulation and experimental measurement show that this method has a good performance in the respects of adjustment time,overshoot and steady-state error.
