Assessing The Potential For Regenerative Control In An Active Vibration Isolation System

这个奖项是为了支持UPI在马萨诸塞州布莱顿的巴里控制公司为期两个月的合作研究工作。在头四周的研究中，PI将审查隔振系统的控制策略；制定现实的控制器和执行器模型；并进行稳健的稳定性分析。该分析将展示PI开发的一种新的分析技术用于解决现实世界的问题。在接下来的五周里，研究将集中在主动隔振系统的功率和能源消耗上。功率需求通过传统控制策略和再生控制策略的各种控制器，可以量化所需功率与闭环系统性能的关系，这对系统设计至关重要。对于再生控制策略，执行器力和执行器速度的乘积，当为正时表示隔振系统所需的功率；当为负时表示施加给系统的功率，即实际可再生的功率。这项研究的一个主要目标是增进对应用于隔振系统的再生控制的理解。

This GOALI award is to support a two-month collaborative research effort of UPI at Barry Controls of Brighton, MA. During the first four weeks of research, the PI will review vibration isolation system control strategies; formulate realistic controller and actuator models; and carry out robust stability analysis. The analysis will demonstrate the utility of a new analysis technique developed by the PI to solve a real world problem. During the next five weeks, the research will focus on power and energy consumption of an active vibration isolation system. Power requirements with a variety of controllers for both conventional and regenerative control strategy, it will be possible to quantify required power versus the performance of the closed- loop system, which is critical for system design. For the regenerative control strategy, the product of actuator force and actuator velocity, when positive--denotes the power required by the vibration isolation system; and when negative-denotes the power to be applied to the system, i.e., power that could actually be regenerated. A major goal of this research is to enhance an understanding of regenerative control as applied to vibration isolation systems.
