9457967 Dawson In this project, the primary focus will be the design and implementation of high precision actuators for manufacturing applications. Specifically, advanced nonlinear position tracking controllers will be developed for several types of electric motors for the actuation of mechanical loads. These nonlinear controllers are designed at the voltage input of the motor; therefore, the electrical dynamics of the motor as well as the mechanical dynamics of the load are both accounted for in the low level control synthesis. The nonlinear control techniques to be considered can be divided into two general categories: (1) controllers which require full state feedback, for example, rotor position, rotor velocity, and per phase currents, and are capable of compensating for system uncertainty, for example, parametric uncertainty and/or system disturbances, and (2) controllers which require only partial state feedback, for example, rotor position only, but rely on perfect knowledge of the entire electromechanical dynamics. The research is expected to lead to advancements in high-performance servo drives using electrical actuators. Machines used in manufacturing applications are expected to benefit from this research.

小行星9457967 在这个项目中，主要重点将是设计和实施高精度致动器的制造应用。 具体而言，先进的非线性位置跟踪控制器将开发用于驱动机械负载的几种类型的电动机。 这些非线性控制器是在电机的电压输入端设计的;因此，电机的电气动态特性以及负载的机械动态特性都在低水平控制合成中考虑。 要考虑的非线性控制技术可分为两大类：（1）需要全状态反馈（例如转子位置、转子速度和每相电流）并且能够补偿系统不确定性（例如参数不确定性和/或系统扰动）的控制器，以及（2）仅需要部分状态反馈的控制器，例如，转子位置，但依赖于整个机电动力学的完美知识。 该研究有望推动使用电动执行器的高性能伺服驱动器的发展。 用于制造应用的机器有望从这项研究中受益。
