针对炉温设定值变化等原因引起的对象模型参数变化,提出一种鲁棒自适应smith预估器.鲁棒项的引入,提高了smith预估器自适应律对纯迟延参数精度的鲁棒性,在纯迟延时间失配的情况下,自适应算法仍能保证预估误差快速收敛.对预估器和电阻炉的仿真结果表明,在纯迟延时间失配的情况下,鲁棒自适应smith预估器能够保证预估误差收敛于零,进而保证系统的控制性能.

Considering the diversification in plant parameters caused by various of factors such as the reference and humidity, a ro-bust adaptive smith predictor is proposed in the Temperature Control System for Resistance Furnace. The robust term ensures the proditor error convergence to zero when the delay time is mismached. Consequently ensures the control performance of the system. Simulation results are given to verify the efficiency.
