摘要
转动惯量决定了动态试验过程的客观性和有效性,电模拟在可控和可调性方面优于机械飞轮组模拟,是未来动态试验中惯量模拟的主流。为展现机械转动惯量电模拟技术的研究成果和促进技术进步,在阐述机械转动惯量电模拟原理的基础上分析了该技术在汽车传动系统试验台和风力机动态特性模拟领域中应用的技术特征,根据参与控制的信号将已研究的控制方法归纳为角加速度控制法、扭矩控制法和转速跟踪控制法,并分析了这些控制方法的特点和存在的问题,从工程应用的角度提出进一步研究需要考虑实际系统中的非线性摩擦及弹性特性、控制所需信号的实时检测、系统延迟的影响及补偿方法。
The moment of inertia determines the objectivity and effectiveness of the dynamic test process.The electrical emulation has the advantages of the tunability and controllability than emulation by the mechanical flywheel groups,and will be the most promising method for the dynamic test in the future.In order to illustrate the research conclusions of the mechanical inertia electrical emulation and promote technological progress,the principle of the electrical emulation was illustrated,and then technology characteristics of the application in the field of vehicle transmission system test platform and the dynamic behavior emulation of wind turbine were analyzed.The researched control methods were summarized as angular acceleration control method,torque control method and speed tracking control method according to the signal take part in the control method.The characteristics of these control methods and the existing problems were analyzed.Furthermore,the key problems being considered in the future researches were proposed from the engineering application aspect.They are the nonlinear friction and elastic properties in actual system,the real-time detection for signal take part in the control method as well as the system time delay effect and compensation method.
