Abstract

The paper discusses the basic requirements and provides calculations and results of modeling and simulation for an electronic control unit of an electrohydraulic power amplifier. It is shown that data exchange interfaces have the greatest influence on the choice of the element base for the implementation of the control unit. In particular, the implementation of the Ethernet interface may cause the greatest difficulty. The organization of the transport and logical levels of exchange in Ethernet is much more complex than, for example, in the RS-485 interface widely used in automation systems. The results of modeling the power part of the control unit, made according to the bridge scheme, using algorithms for pulse voltage regulation on the armature winding of an electromechanical converter are presented. A step-up voltage converter has been introduced into the power unit, controlled synchronously with a bridge converter to reduce the influence of electromagnetic radiation on the information components of the control unit. A dynamic model of a tracking system for regulating the position of the spool is investigated.

电液功率放大器控制单元的需求定义、建模和仿真

本文讨论了基本要求，并提供了电液功率放大器电子控制单元的建模和仿真计算及结果。结果表明，数据交换接口对选择实施控制单元的元素基础影响最大。特别是以太网接口的实施可能会造成最大的困难。以太网的传输和逻辑交换层的组织要比自动化系统中广泛使用的 RS-485 接口复杂得多。本文介绍了根据电桥方案，利用机电转换器电枢绕组脉冲电压调节算法对控制单元的电源部分进行建模的结果。功率单元中引入了升压变流器，与桥式变流器同步控制，以减少电磁辐射对控制单元信息组件的影响。研究了用于调节转轴位置的跟踪系统的动态模型。
