摘要

本文讨论了两种主动阻尼控制策略在抑制同步自由活塞斯特林发动机/线性交流发电机在较宽带宽[47-53]Hz至低于20μm振幅范围内的振动方面的性能。在此基础上，建立了斯特林发动机发电机的简化振动模型，并验证了该模型的响应与实际模型吻合较好。在时域和频域对两种主动控制技术进行了讨论和分析。第一种控制策略是基于前馈零位置控制，第二种是线性二次(LQ)最优控制和状态观测器。

Active vibration control strategies for a Free Piston Stirling Engine generator

This paper discusses the performance of two active damping control strategies in mitigating the vibration of a synchronous Free-Piston Stirling Engine/Linear Alternator over a wider bandwidth [47-53] Hz to amplitudes below 20μm. A simplified vibration model of the Stirling engine generator is justified on the basis that the response of the proposed model is verified to match well that of the real one. Two active control techniques are discussed and analyzed in the time and frequency domains. The first control strategy is based on a Feed-forward zero-placement control whereas the second one is linear quadratic (LQ) optimal control and state observer.
