Title: The Innovative Mind of Steven R. Popovich
Introduction
Steven R. Popovich is a notable inventor based in Stoughton, Wisconsin, with a remarkable portfolio of 11 patents. His work primarily focuses on adaptive control systems and active acoustic control technologies, showcasing his expertise in engineering and innovation.
Latest Patents
One of his latest patents is titled "Adaptive control system with efficiently constrained adaptation." This invention implements a back-projection technique to limit the adaptation of parameters within the system, ensuring that actuators do not exceed desired physical limitations. When the optimal controller solution is outside a designated region in the parameter space, adaptation is back-projected onto a smooth convex surface that defines the edge of this region. This method enhances convergence by normalizing adaptation and compensating back-projection accordingly. Additionally, to reduce computational burdens, adaptation is processed using a time-sharing technique that handles orthogonal components separately.
Another significant patent is "Active acoustic control in remote regions." This invention addresses the challenge of controlling acoustic disturbances in areas distant from an error sensor. By utilizing an adjusted error signal from a remote sensor, the adaptive control filter is updated to drive an output transducer. This transducer generates a secondary input that destructively interferes with and cancels the acoustic disturbance. The invention includes various embodiments, such as feedforward and regenerative feedback systems, as well as single-input single-output (SISO) and multiple-input multiple-output (MIMO) configurations.
