Matlab/Sinulink仿真性能与计算精度设置方法的研究

Research on Matlab/Sinulink Simulation Performance and Computation Precision Establishment Method

仿真性能和计算精度受到诸多因素的影响。通过设置步长和误差等方法来加速Simulink仿真,采用缩小步长、选择合理的求解器和设置较小的相对误差来提高Simulink精度,采用尽量避免使用循环、给大型矩阵预先定维和优先考虑内在函数等方法来加速Matlab的计算速度。该方法可从很大程度上提高编程和仿真执行速度和运行效率。

Matlab and Simulink simulation performance and calculation precision are often influenced by many factors. By setting steps and error method to accelerate the Simulink simulation,reducing the length of steps,choosing reasonable solution,and establishing a smaller relative error,the Simulink precision was increased to avoid the use of circulation as possible, pre-determine large matrix peacekeeping and prior to consider the inherent function method and so on. Accelerating the speed of Matlab can largely enhance the implementation of programming and simulation speed and operating efficiency.
