Abstract This paper presents an optimal motion control scheme for a mechatronic actuator based on a dielectric elastomer membrane transducer. The optimal control problem is formulated such that a desired position set-point is reached with minimum amount of driving energy, characterized via an accurate physical model of the device. Since the considered actuator is strongly nonlinear, an approximated approach is required to practically address the design of the control system. In this work, an Adaptive Dynamic Programming based algorithm is proposed, capable of minimizing a cost function related to the energy consumption of the considered system. Simulation results are presented in order to assess the effectiveness of the proposed method, for different set-point regulation scenarios.

AbstractThis paper studies the online learning control of a truck-trailer parking problem via adaptive dynamic programming (ADP). The contribution is twofold. First, a novel ADP method is developed for systems with parametric nonlinearities. It learns the optimal control policy of the linearized system at the origin, while the learning process utilizes online measurements of the full system and is robust with respect to nonlinear disturbances. Second, a control strategy is formulated for a commonly seen truck-trailer parallel parking problem, and the proposed ADP method is integrated into the strategy to provide online learning capabilities and to handle uncertainties. A numerical simulation is conducted to demonstrate the effectiveness of the proposed methodology.
