摘要

为了有效地控制直线冰箱压缩机的活塞位移

提出了一种以活塞上死点位移为控制目标的可自调整规则的模糊控制系统.基于模糊控制模型和活塞运动模型

开发了模糊控制系统的硬件和软件

控制系统主要由位移测量模块、中央处理器模块、功率驱动模块、电源模块及上位机等组成.为了研究模糊控制系统的性能

实验测量了其响应曲线

实验结果表明:模糊控制系统在无需压缩机系统模型的前提下

可以成功地控制直线压缩机的活塞位移

其在上死点附近几乎无超调

稳态误差小于0.25 mm.这种新型的模糊控制系统对于冰箱、空调、斯特林制冷机及气体等领域的直线压缩机活塞位移控制具有很大的应用前景.

Abstract

In order to effectively control the piston displacement of a linear refrigerator compressor

a new fuzzy control system based on self-adjusting was proposed. The hardware and software of the fuzzy control system were developed with the piston motion model and the fuzzy control model. The control system is mainly composed of a displacement measurement unit

a DSP

a power driver unit

an electricity source unit

and a computer. The response curve of the fuzzy control system was measured. The experimental results show that the present control system can effectively measure and control the piston stroke and the top clearance distance of the linear compressor. The steady-state error of the top clearance distance is smaller than 0.25 mm

and there is almost no overshoot nearby the top dead center.
