Experimental validation of an L1 controller on a single robotic manipulator on a moving platform and a robotic cooperative network
… theoretical predictions for the dependence on control parameters of an L1 adaptive control strategy. The experiments verify expected bounds on the tracking error in terms of the bandwidth of a filter introduced in the control loop. Moreover, the results provide insight into different …

Solar Sailing Adaptive Control Using Integral Concurrent Learning for Solar Flux Estimation
… spacecraft missions, this thesis proposes an adaptive control strategy to account for unknown parameters in the dynamic modeling of a reflectivity-controlled solar sail spacecraft. A Lyapunov-based control law along with integral concurrent learning is suggested to accomplish and prove global …

Data-Driven, Non-Parametric Model Reference Adaptive Control Methods for Autonomous Underwater Vehicles
This thesis details the implementation of two adaptive controllers on autonomous underwater vehicle(AUV) attitude dynamics starting from the standard six degree-of-freedom dynamic model. I apply two model reference adaptive control (MRAC) algorithms which make use of kernel functions for learning …
