摘　　要：非线性和不确定性是制约控制系统性能的主要因素,为此出现了许多方法都试图克服这些因素的影响.本文提出一种基于偏差分离的双线性控制策略,在线获取模型偏差信息,并采用简单的双线性控制结构,具有很好的工程意义.论文证明了双线性控制系统指数渐近稳定的充分条件.仿真结果表明所提出的双线性控制策略的有效性.Nonlinearity and uncertainty are the main factors which restrict the system performance. There are many methods to attempt to overcome the impact of these factors. A bilinear control strategy based on model bias separation is proposed in this paper. The bilinear control obtains the model bias information on line, and adopts a simple bilinear control structure. So it has good engineering significance. The sufficient condition for system exponential stability has been proved. The simulation results show the effectiveness of the proposed bilinear control strategy.
