Learning open-loop from closed-loop control
This paper explores an evolution from closed-loop control to open-loop control for a planar manipula-tor. A reinforcement learning strategy is used to learn the open-loop commands from the closed-loop control. The goal is to produce a motion using purely open-loop control strategy, thereby eliminating the need for inter-link communication and on-line control computations. Initially closed loop ...
متن کاملOpen-loop and Closed-loop Optimization of Linear Control Systems
A canonical optimal control problem for linear systems with timevarying coefficients is considered in the class of discrete controls. On the basis of linear programming methods, two primal and two dual methods of constructing optimal open-loop controls are proposed. A method of synthesis of optimal feedback control is described. Results are illustrated by a fourth-order problem; estimates of ef...
متن کاملReinforcement Learning for Mixed Open-loop and Closed-loop Control
Closed-loop control relies on sensory feedback that is usually assumed to be free . But if sensing incurs a cost, it may be costeffective to take sequences of actions in open-loop mode. We describe a reinforcement learning algorithm that learns to combine open-loop and closed-loop control when sensing incurs a cost. Although we assume reliable sensors, use of open-loop control means that action...
متن کاملHigh-Performance Visual Closed-Loop Robot Control
This thesis addresses the use of monocular eye-in-hand machine vision to control the position of a robot manipulator for dynamically challenging tasks. Such tasks are defined as those where the robot motion required approaches or exceeds the performance limits stated by the manufacturer. Computer vision systems have been used for robot control for over two decades now, but have rarely been used...
متن کاملOpen-loop and closed-loop filters for optimal trajectory planning under time and frequency constraints
Dynamic filters for real-time trajectory generation can be designed in different ways with quite different levels of performances and complexity. However, one can observe that the configurations of such filters are based on two main schemes: systems composed of a chain of integrators with a feedback control and systems formed of a sequence of linear filters disposed in a cascade configuration. ...
