To track the molecular weight distribution in threedimensional space, we propose a new method employing a generalized state-feedback controller. By the hybrid dynamic recurrent supportvectormachine model, the distribution function is effectively separated into aspects of time and space. Thus, the tracking of threedimensional distribution will be transformed into a statevector tracking in the time domain; and the control difficulty will be greatly reduced. A combi nation configuration of the statefeedback controller and the integrator is proposed, the linear matrix inequality techniques are employed to design the parameters; and the stability and tracking performances can be guaranteed simultaneously. Simulation results of a polymerization reaction process show the efficacy of the proposed method.%针对化工过程中分子量分布的跟踪控制问题，提出了一种简单的广义状态反馈控制方法，实现给定分子量分布的跟踪．该方法充分利用复合动态支持向量机模型，实现分子量分布函数在时间域和空间域上的分离，从而将分布函数的跟踪问题转化为动态权值向量的时间域跟踪问题，并设计了状态反馈与积分器相结合的控制结构，采用线性矩阵不等式技术对闭环系统稳定性和跟踪性能进行分析．仿真结果表明该方法的可行性．
