Abstract: This letter proposes an algorithm for solving finite-time nonlinear optimal control problems. The proposed method employs the Gauss pseudospectral method to transform the optimal control ...

Abstract: In this article, we investigate the optimal control problem for an unknown linear time-invariant system. To solve this problem, a novel composite policy iteration algorithm based on adaptive ...

The tension of conventional surgical sutures can affect wound healing and is dependent on the surgeon’s experience. Imaging and simulations reveal that slipknots can reproducibly store and release ...
