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.

该GOALI奖将支持UPI在马萨诸塞州布莱顿的Barry Controls进行为期两个月的合作研究。在研究的前四周，PI将审查隔振系统控制策略；制定真实的控制器和执行器模型；并进行鲁棒稳定性分析。该分析将演示PI开发的一种新的分析技术在解决现实世界问题中的实用性。在接下来的五周内，研究将重点放在主动隔振系统的功率和能耗上。对于传统和再生控制策略的各种控制器的功率需求，将有可能量化所需的功率与闭环系统的性能，这对系统设计至关重要。对于再生控制策略，致动器力与致动器速度的乘积为正时——表示隔振系统所需的功率；负表示应用于系统的功率，也就是说，实际上可以再生的功率。本研究的一个主要目标是提高对应用于隔振系统的再生控制的理解。
