模型跟随自适应控制在电液伺服板簧试验机中的应用

Adaptive Model Following Control of an Electrohydraulic Servo Tester with Laminated Spring

通过对电液伺服板簧试验机系统进行理论分析和试验研究，采用新的模型跟随自适应控制方法，有效地解决了电液伺服板簧试验机中波形严重失真、难以使用和试验加载频带低的问题，使加载频带从０１～３Ｈｚ提高到０～２０Ｈｚ．

An electrohydraulic servo tester is developed using laminated spring. A new adaptive control approach is used to overcome the excessive distortion of the waveform enabling the coverage of 0～20 Hz bandwidth for the tester. Satisfactory results have been obtained.
