摘　　要：MATLAB软件在许多科学领域中成为计算机辅助设计、算法研究和应用开发的基本工具,在MATLAB/Simulink中对线性定常系统或者简单的非线性控制系统的建模与仿真比较简单方便,但对复杂非线性控制系统的建模与仿真实现困难。提出一种在MATLAB环境下利用m函数实现非线性控制系统的建模与仿真方法,该方法简单直观,维护性较好,具有可移植性。对复杂的非线性控制系统的建模与仿真,该方法可以明显提高仿真的效率。仿真实例验证了该方法的有效性和可行性。The MATLAB software is the basic tool for computer- aided design, algorithm study and applications exploitation in many scientific areas. It is simple and convenient for the modeling and simulation of linear time- invariant system or simple nonlinear control system in MATLAB/Simulink. But it is difficult for the realization of modeling and simulation of complex nonlinear control systems. A method of modeling and simulation of nonlinear control systems using m - ftmction in MATLAB environment is presented. The method is simple and intuitive, and has a better ability of maintenance, and has the ability of naturalization. The efficiency of simulation can be improved evidently for the modeling and simulation of complex nonlinear control systems by using the presented method. Simulation example demonstrates the effectiveness and the feasibility of the presented method.
