Latest Patents

Austin's latest patents include a "Robust controller for electro-mechanical actuators employing sliding and second control modes." This invention combines a sliding mode of control with a secondary control mode to enhance the performance of electro-mechanical actuators. The controller generates an error signal based on the difference between an input position signal and a feedback position signal. When the error signal exceeds a predetermined threshold, the actuator operates in sliding control mode. Conversely, when the error signal is below the threshold, the actuator switches to the second control mode. This innovative combination allows for a robust controller capable of tolerating significant parameter variations and uncertainties while maintaining precise steady-state tracking.

Another notable patent is the "Controller for actuation system employing Kalman estimator incorporating effect of system structural stiffness." This invention features a Kalman estimator circuit that generates estimates of the operating state, including the position and velocity of the motor and the position-controlled element (PCE). The dynamic model explicitly accounts for structural stiffness and damping effects in the coupling between the motor and PCE. The Kalman estimator processes motor drive control signals and measured position signals, optimizing control efforts through a linear quadratic regulator circuit.
