摘要：

为了提高加热炉炉温控制精度,设计集成干扰观测器的BP-PID控制器.通过干扰观测器观测出等效干扰,在BP-PID控制器输入端引入等效的补偿,构成一种新的控制器.该控制器继承了BP-PID控制器的智能性,能够对工况进行学习识别,使输入功率逐渐逼近当前的耗散功率,并在耗散功率附近小幅波动,达到动态平衡状态；同时具有干扰观测器抑制干扰的特性,可以对进料、卸料等干扰进行实时估计和补偿,弥补了单纯BP-PID控制器收敛慢、鲁棒性差的缺陷.仿真和实验结果均表明,该控制器可以自动适应各种工况条件,具有很高的稳态精度,对大范围的负载扰动具有很强的抑制作用.
Abstract:

A disturbance observer based BP-PID controller was designed in order to enhance the control precision of furnace temperature. An equivalent compensation was introduced in the input of the BP-PID controller to form a new controller by determining the equivalent disturbance through the disturbance observer. The controller inherited the capacity of BP-PID controller to recognize the working condition. The input power gradually approached to the current dissipated power and fluctuated around the dissipated power with small scale, and finally reached the state of dynamical equilibrium. The controller was also a characteristic disturbance inhibitor to estimate and compensate the disturbances in the control process such as load in, load out and so on, which make up for the flaw of simple BP-PID controller such as slow convergence and bad robustness. The simulation results accorded with the experimental results. The controller can automatically adapt to each kind of working condition and maintains very high precision at stable state. The controller can strongly inhibit from the large range of payload disturbances.
