IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.Heating, ventilation and air conditioning (HVAC) chilled water systems have great energy‐saving potential, and while reinforcement learning (RL) is widely studied for optimizing their energy consumption, RL's low sample efficiency and dependence on randomized exploration restrict its practical use. To address this, a RL optimization approach based on a

Hamilton–Jacobi–Bellman Equation under States Constraints
Journal of Mathematical Analysis and Applications, 2000 This paper is concerned with the uniqueness of discontinuous solutions of the Hamilton-Jacobi-Bellman equation \[ \begin{cases} -{\partial V\over\partial t} (t,x)+ H(t,x,{\partial V\over\partial x}(t, x))= 0,\\ V(t,x)= \psi(x)\text{ when }g(T,x)\leq 0,\end{cases} \] where \(H(t,x,p)= \sup_{v\in F(t,x)}\langle p,v\rangle\), arising in Mayer's problem ...
