RISOn the Structure of the Optimal Solution to a Periodic Drug-Delivery Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the shaping of a drug's delivery—in this case, nicotine—to maximize its efficacy. Previous research: (i) furnishes a pharmacokinetic–pharmacodynamic (PKPD) model of this drug's metabolism; (ii) shows ...
Demand Response Using Heterogeneous Thermostatically Controlled Loads: Characterization of Aggregate Power Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents an analysis of the damping and beating effects within the aggregate power demand of heterogeneous thermostatically controlled loads (TCLs). Demand response using TCLs is an appealing method to enable ...
A Computationally Efficient Approach for Optimizing Lithium Ion Battery Charging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a framework for optimizing lithiumion battery charging, subject to side reaction constraints. Such healthconscious control can improve battery performance significantly, while avoiding damage phenomena, ...
Optimal Boundary Control of Reaction–Diffusion Partial Differential Equations via Weak Variations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper derives linear quadratic regulator (LQR) results for boundarycontrolled parabolic partial differential equations (PDEs) via weak variations. Research on optimal control of PDEs has a rich 40year history. This ...
Extremum Seeking for Plants With a Time-Varying Disturbance: Application to Photovoltaic Maximum Power Point Tracking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an extremum seeking controller for photovoltaic maximum power point tracking (MPPT). The controller belongs to the broad family of “perturb and observe” algorithms, where the terminal voltage of a ...
