| 中文摘要 |
| 针对热连轧板宽板厚多变量系统存在强耦合、大时滞和随机不确定等难题, 提出了一种线性自抗扰动态解耦方案. 考虑到系统的大时滞问题, 在常规的降阶扩张状态观测器(ESO)之前, 增加了一个纯时滞环节. 为了把所设计的实用自抗扰控制(ADRC)与常规PID控制器进行公平比较, 各控制器的最佳参数均采用变尺度混沌优化方法得到. 仿真结果表明, 优化后的ADRC不仅具有较好的解耦性能, 而且对模型参数的不确定性和外扰具有较强的鲁棒性和参数适应性. |
| 英文摘要 |
| To deal with the strong interactions between loops, large time-delay and random uncertainties in the multivariable system of the hot rolling mill, we propose a solution of active disturbance-rejection control (ADRC). In this solution, a time-delay unit is added before the conventional reduced-order extended-state observer. For the fair comparison of the proposed ADRC and the conventional PID controller, parameters of each algorithm are obtained by using the mutative-scale chaotic optimization method. Simulation results show that the optimized ADRC not only has better decoupling performance, but also provides higher robustness and adaptability against the model-parameter uncertainties and external disturbances. |
