Adaptive dynamic programming with eligibility traces and complexity reduction of high-dimensional systems
… techniques, particularly clustering and adaptive dynamic programming (ADP) designs especially heuristic dynamic programming (HDP) and dual heuristic programming (DHP). Moreover, a one-step temporal-difference (TD(0)) and <em>n</em>-step TD (TD(λ)) with their gradients are utilized as …

Stochastic optimal adaptive controller and communication protocol design for networked control systems
… a suite of novel stochastic optimal adaptive design methodologies is undertaken for both linear and nonlinear NCS in presence of uncertain system dynamics and unknown network imperfections such as network-induced delays and packet losses. The design is introduced in five papers.</p> …

Methods Of Distributed And Nonlinear Process Control: Structuredness, Optimality And Intelligence
… by sparse optimal control of Laplacian network dynamics. Community detection-based methods are proposed for input--output bipartite and variable-constraint network representations and applied to a benchmark chemical process. 2. For the optimality of control, we first derive a computationally …

Value-Gradient Learning
This thesis presents an Adaptive Dynamic Programming method, Value-Gradient Learning, for solving a control optimisation problem, using a neural network to represent a critic function in a large continuous-valued state space. The algorithm developed, called VGL(λ), requires a learned differentiable …

Virtual Inertia Emulation to Improve Dynamic Frequency Stability of Low Inertia Microgrids
… the intermittent nature of photovoltaic systems, dynamic frequency stability issues arise in microgrids with large photovoltaic systems. This limits the maximum amount of photovoltaic systems that can be penetrated in the microgrid. In order to increase the penetration of photovoltaic systems, the …
