缸内直喷航空活塞发动机接口模拟器设计

Design of Interface Simulator for GDI Aviation Piston Engine

为建立发动机控制系统实物仿真试验环境,设计基于DSP的接口模拟器。采用该接口模拟器,结合发动机模型和控制器实物,构成完整的实物在回路仿真系统。仿真实验表明:模拟器能够传递控制器和上位机之间的信息,具有良好的实时性和抗干扰能力,满足系统设计需要。

An interface simulator based on DSP is designed to establish an environment for engine control system simulation test. Based on the interface simulator, together with engine model and real controller, it forms the whole hardware-in-loop simulation experiment system. The results of the simulation show that the interface simulator can convey information between controller and PC. The system is a real-time and high robust one, which can meet the requirement of the equipments.
