摘要
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
