A hybrid formulation for blended adaptive feedforward and feedback closed‐loop control

Adaptive Feedforward and Feedback Control for Cloud Services

The use of cloud services is becoming increasingly common. As the cost of these services is continuously decreasing, service performance is becoming a key differentiator between providers. Solutions that aim to guarantee Service Level Objectives (SLO) in term of performance by controlling cluster size are already used by cloud providers. However most of these control solutions are based on stat...

Hybrid Feedforward-Feedback Noise Control using Virtual Sensors

Genetic Feedforward-Feedback Controller for Functional Electrical Stimulation Control of Elbow Joint Angle

Background: Functional electrical stimulation (FES) is the most commonly used system for restoring functions after spinal cord injury (SCI). Objective: In this study we investigated feedback PID and feedforward-feedback P-PID controllers for regulating the elbow joint angle. Methods: The controllers were tuned based on a nonlinear muculoskeletal model containing two links, one joint with one de...

A General Adaptive Feedforward Compensation Algorithm for Active Vibration Control with Mechanical Coupling and Local Feedback

Adaptive feedforward broadband vibration (or noise) compensation is currently used when a correlated measurement with the disturbance is available. Most of the active vibration control systems feature an internal ”positive” mechanical feedback between the compensation system and the reference source (a correlated measurement with the disturbance). Such systems have often also a feedback control...

Feedback and Feedforward Tracking Control for Networked Control Systems

Abstract— In this paper, we investigate the feedback and feedforward tracking control problem for networked control systems under the discrete-time framework. The network-induced delays both on the network links from sampler to the controller and from the controller to the actuator are considered. By studying the network property, we assume that there is a probability for the occurrence of each...
