摘要
自抗扰控制器(ADRC)不依赖被控对象模型,具有很好的鲁棒性,特别是对于大时滞对象的控制特别有效,但是一套控制器参数无法控制所有温度对象。通过对实际温度对象分析和仿真,提出了用10套控制器参数控制所有温度对象的思想,并把这种思想应用到智能温度控制器设计中。控制器在参数自整定阶段从10套控制器参数中寻找性能指标最优的参数投入运行。通过仿真和实时控制表明,所设计的智能温度控制器对不确定温度对象具有良好的控制效果。
A plant without accurate mathematical model can be controlled by the auto disturbance rejection controller （ADRC） which can give effective control for the plants with large delay. But all temperature plants canlt be controlled by the controller with one set parameters of ADRC. Ten sets parameters of ADRC which can control all the temperature plants were presented by analyzing the temperature plants. The intelligent controller controls uncertain temperature plants by searching the parameter with the best performance index from the ten sets parameters. The emulation and real-time control indicate that the intelligent controller controls uncertain temperature plants effectively.
