Control-Loop Design for Nonlinear Sensors

摘要

While linear control theory is well developed, the practice of restricting systems to operate solely in linear regions can seriously limit the achievable performance. New technologies and new applications would be enabled by better understanding of the closed-loop control of nonlinear systems. If robust control loops can be designed in the presence of these nonlinearities and points of instability, the performance of these systems can be enhanced significantly. For example, controlled operation in or near regions of inherent instability can result in improved bandwidth, response time, and a wider envelope of operation.
