Abstract
For today's industry, system simulation is an integral part of design and implementation. This is a process that often involves tight coupling between hardware, interface, and algorithmic adaptation. This paper discusses the design and implementation of a plant/process simulator on an integrated mbed LPC1768 based microcontroller platform. Unlike simulators such as MATLAB, Scilab, Scicos, Ecosim Pro, Virtual Control Simulator, etc. that are installed on a computer, the simulator is implemented on a portable, low-cost embedded microcontroller. The method of simulation is convolution via FFT/IFFT using the Radix-2 DIT Cooley-Tukey algorithm. Our implementation is verified using both step and sinusoidal inputs. The results of the simulator are compared to MATLAB outputs as the reference for accuracy determination.
对于当今的工业，系统仿真是设计和实现的一个组成部分。这个过程通常涉及硬件、接口和算法适应之间的紧密耦合。本文讨论了基于集成mbed LPC1768微控制器平台的工厂/过程模拟器的设计与实现。与MATLAB、Scilab、Scicos、Ecosim Pro、虚拟控制模拟器等安装在计算机上的模拟器不同，该模拟器是在便携式、低成本的嵌入式微控制器上实现的。仿真方法是使用Radix-2 DIT Cooley-Tukey算法通过FFT/IFFT进行卷积。我们的实现使用步进和正弦输入进行了验证。仿真结果与MATLAB输出进行比较，作为确定精度的参考。
