Latest Patents

David G Ward holds a patent for a "System for improved receding-horizon adaptive and reconfigurable control." This invention focuses on the adaptive and reconfigurable control of aircraft and other complex objects, collectively referred to as controlled "plants." The system employs a modified form of sequential least-squares estimation to provide near-real-time estimates of plant parameters. These estimates are utilized in a novel piecewise-linear optimal receding-horizon sampled-data controller. This method represents a significant advancement over prior art, as it updates Riccati gains based on the most recent parameter estimates rather than re-initializing them at each control update. The invention offers improved control robustness, reduces the need for re-tuning, and lessens computational burdens, making it suitable for on-line adaptation to changing conditions.
