制粒机的无模型自适应控制

制粒机生产过程是一个大滞后、多变量的难控系统,常规的控制系统难以取得理想的控制效果,而无模型自适应控制器具有良好的输出跟踪性能,有很强的自适应能力和鲁棒性,能有效的控制复杂过程。将无模型自适应(MFA)控制器应用到扬州市某饲料厂的制粒机自动控制系统中,进行了长时间的试生产,试验结果表明MFA控制系统可以有效克服双回路耦合及大滞后带来的影响,取得了良好的控制效果。

Model free adaptive (MFA) control of the pelletizer

The production of pelletizer is a multi-variable process with large time delays,the conventional control can not meet the request of production,but the MFA controller which can control complex process effectively has a good track performance,adaptive capacity and robustness.MFA controller was adopted in an automatic control system of pelletizer,which located in a Feed-processing plant of Yangzhou.Experiments showed that MFA control system obtained a good performance which overcame the disturbances of the 2x...
