To do this a controlleris designed, which monitors the output and compares it with the reference.

The theory of optimal control is concerned with operating a dynamic system at minimum cost. The case where the system dynamics are described by a set of linear differential equations and the cost is described by a quadratic function is called the LQ problem. One of the main results in the theory is that the solution is provided by the linear–quadratic regulator (LQR), a feedback controller whose equations are given below. WebModel Predictive Control (MPC) is a powerful optimization strategy for feedback control. The principle behind MPC is the following: if you have a model of your system of interest, …
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 WebDec 1, 2002 · This paper presents a computational model of this neurobiological component, based on the theory of stochastic optimal feedback control (OFC).
