WebJul 1, 2004 · An optimal feedback controller uses an optimal estimate of the state of the system, generated through sensory feedback and efferent copy, and uses this feedback … In a wide range of tasks, variability is not eliminated, but instead is allowed to accumulate in task-irrelevant (redundant) dimensions. Our explanation of this phenomenon follows from an intuitive property of optimal feedback control that we call the 'minimal intervention' principle: deviations from the … See more The exploitation of mechanical redundancy in Fig. 1 occurs under static conditions, relevant to postural tasks in which this phenomenon has indeed been observed6. Here the … See more Unlike the extensively studied case of mechanical redundancy, the case of endpoint trajectory redundancy has received significantly less attention. Here we investigate the … See more Although our work was motivated by the variability patterns observed in redundant tasks, the optimal feedback controllers we constructed displayed a number of additional properties … See more The most complex form of redundancy is found in object manipulation, where the task outcome depends on the state of the controlled object, which may in turn reflect the entire history of … See more
WebThe method is applied to a DC motor/AC generator system. The effectiveness of the method is demonstrated by simulation and experimental studies. An input-output relation is derived through the observable canonical form of the state equations of the controlled object, and an improved optimal regulator theory is applied to the relation. WebApr 5, 2024 · Optimal control theory is a branch of control systems design that aims to find the best possible control inputs for a given system and objective. It has applications in diverse fields...
Webrepresents the optimal cost, any admissible perturbation of y must hit the S0 1 manifold higher up. It is impossible for the perturbed trajectory yto hit S0below y(t) (see right hand side of figure1). The basic plan of the proof is as follows. We first introduce a very special set of perturbations on the control uand the terminal time t f ... WebApr 13, 2024 · Optimal control theory describes control strategies to steer a system towards an optimal outcome specified in a cost function [48, 49]. In an optimal control problem, state variables x ( t ) depending on time t , model a dynamical system and appropriate control function u ( t ) is obtained by optimizing an objective function J ( u ) subject to ...
