Perceptron(linear and non-linear) andRadial Basis Function networksare examples of feedforward networks. A single-layer perceptron network is the most basic type of neural network. It has a single layer of output nodes, and the inputs are fed directly into the outputs via a set of weights. ...
The effects of the constraint of causality on the performances of feedforward and feedback control of random disturbances are discussed using two simple examples; a minimum phase single-degree-of-freedom vibrating system and a non-minimum phase acoustical system....
This paper presents an efficient hybrid feedback feedforward (HFF) adaptive approximation-based control (AAC) strategy for a class of uncertain Euler–Lagrange systems. The control structure includes a proportional–derivative (PD) control term in the feedback loop and a radial-basis-function (RBF...
Formula for the F/P control gains are derived using a parameter optimization technique to minimize a quadratic cost criterion. Simulation examples are included to show some of the consequences of the developed design method. 展开 关键词: Design Control equipment Feedback Feedforward control Simulation...
Examples of cyclic Eulerian numbers for values of k up to 9 are also presented later in Methods. The expected fraction F(k,γ) of loops of length k which are feedback loops can be expressed as where the two terms in square brackets account for the two different possible orientations of...

This value is used as the feedforward gain for the current time step. Numerical examples are presented to show the effectiveness of this adaptive control scheme. The effects of varying the control objectives, the updating time for the feedforward gain, and the number and location of actuators ...
