二冲程发动机具有机械效率高,旋转力矩变化较小,运转平稳,机械结构简单,重量轻等优点,适合作为小型无人机、超轻型飞机和动力翼伞等飞行器的动力装置。本文对德国产Hirth3203E二冲程发动机开展了充分的实验研究,采用机理建模和试验建模相结合的方法建立了该发动机均值数学模型,并在Matlab/Simulink环境下对该模型进行了仿真研究。在VC环境下编写仿真软件,通过调用MATLAB引擎实现了模型与控制器的对接,将原控制器和开发的快速原型控制器用发动机模型开展了实物在回路仿真实验,并进行对比分析。
Two-stroke engine with high mechanical efficiency, small changes in torque, smooth operation, simple mechanical structure, light weight and other advantages, suitable as a small UAV, ultralight aircraft and power wing umbrella and other aircraft power plant. In this paper, the German Hirth3203E two-stroke engine to carry out a full experimental study, the use of a combination of mechanical modeling and experimental modeling method to establish a mathematical model of the average engine, and the Matlab / Simulink environment simulation of the model. In the VC environment, the simulation software was written. The MATLAB engine was used to connect the model and the controller. The original controller and the developed rapid prototyping controller were used to simulate the actual circuit in the engine and the comparative analysis was carried out.
