摘要
分析了时变、大滞后系统特性,通过对现有较为成熟可靠的智能自整定PID调节控制算法、Smith预估控制算法以及最小二乘参数辨识法进行深度组合,达到了在增加较小运算量的前提下克服大滞后及时变特性给系统带来不利影响、优化系统软硬件配置的目的。针对飞机除冰车快速加热系统的计算机温度控制仿真结果表明获得了令人满意的控制效果。
The feature of time-varying and time-delaying system was analyzed. By deeply coupling the mature control technology of parameter intelligent self-tuning PID regulation, Smith predictor and LS parameter online identification overcame the disadvantageous effects by time-varying and time-delaying within less operand increase and thus optimized the software and hardware disposes, Computer temperature control simulation shows that this arithmetic has obtained satisfactory control effect in instant heating system for aircraft deicing vehicle.
