This paper presents a fundamental sudy on the application of the model refernce adaptive control system (MRACS) to a mineral plant. The PID regulator is frewuently used in the plant. However, if is not available on the time-varying plant. because the PID parameters are usually necessary to be readjusted. Then, the MRACS is trid to apply in the plant. it automatically readjusts its parameters, but it is not robust to the randow noise. A mineral processing plant is usually time-varying, and theid input/output signals contain random noises. Therefore, it is necessary to improve the robustness to the noise on the application of the MRACS. Peterson et. al. (1982) presented a robust MRACS with a dead zone to the adaptation algorithm. However, this system can not be used without knowledge for the noise.This paper describes a method which corrects this defect and its application to the PH-conditioned process in a mineral processing plant. Some simulation results are illustrated to show the effectiveness of the presented control method. And next, PHconditioned process was set up and connected with a flotation tester. Then, the PH value was actually measured at the tester. The results show that this control method is available on the time-verying plant, and robust to the random noise.

本文对模型自适应控制系统（MRACS）在某选矿厂的应用进行了初步研究。PID调节器在工厂中使用较多。然而，如果是不可用的时变植物。因为PID参数通常需要重新调整。然后，尝试将MRACS应用于工厂。它会自动重新调整其参数，但对随机噪声的鲁棒性较差。选矿厂通常是时变的，并且其输入/输出信号包含随机噪声。因此，有必要提高MRACS应用中对噪声的鲁棒性。彼得森等等人（1982）提出了一种鲁棒的自适应MRACS算法，该算法在自适应算法中存在死区。本文介绍了一种改进方法及其在选矿厂PH调节过程中的应用。仿真结果表明了该控制方法的有效性。其次，建立了PH调节工艺，并与浮选试验机连接。然后，在测试仪上实际测量PH值。结果表明，该控制方法对时变对象是有效的，对随机噪声具有鲁棒性。
