摘　　要：本文首先建立了生物发酵过程的仿射非线性数学模型,然后采用微分几何精确线性化理论,把非线性系统转化成了一个线性系统,最后在此基础上应用非线性变结构控制理论指数趋近律法进行设计,实现了一种较新的对发酵过程的控制。仿真结果表明,该控制系统具有良好的动静态性能。First, the nonlinear model of the biologic fermentation process was built. Then the nonlinear system was I/O linearized by differential geometry transmission. The nonlinear system was turned to a new linear system. Finally a controller of the system is designed according to the method of the exponentially approaching rule of variable structure theory. To verify the effectiveness of the control scheme, some simulations were carried out and the results show satisfactory static and dynamic performances of the system.
