摘要
本文对一类双线性系统，用加权最小二乘辨识方法建立了自适应控制算法，该算法适用于非最小相位系统，且具有大范围渐近收敛和稳定的性质。从谷氨酸结晶过程的ｐ值控制实验表明，本文算法具有良好的控制效果，比非线性ＰＩＤ控制具有更高的控制质量．
In this paper, a stable and convergent adaptive control for minimum or nonminimum bilinear systems is established by using weighted least squares. The effectiveness of the proposed algorithm is demonstrated by its successful application to a pilot glutamic acid crystalization process. It gives much better performance than PID control.
