Disturbance Observer-Based Actor–Critic Reinforcement Learning with Adaptive Reward for Energy-Efficient Control of Robotic Manipulators

Actuators
Reinforcement learning controllers for robot manipulators depend strongly on reward tuning, and fixed weights may yield poor trade-offs under uncertainty and disturbances.

The uniform boundedness theorem and a boundedness principle [PDF]

, 2011
We deal with a form of the uniform boundedness theorem (or the Banach-Steinhaus theorem) for topological vector spaces in Bishop's constructive mathematics, and show that the form is equivalent to the boundedness principle BD-N, and hence holds not only ...

Boundedness of Vector Linéard Equation with Multiple Variable Delays

Mathematics
In this article, we consider a system of ordinary differential equations (ODEs) of second order with two variable time delays. We obtain new conditions for uniform ultimate bounded (UUB) solutions of the considered system.
