Gain-Scheduling Control for Extending Space Structures

Fuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve

Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...

Fuzzy Gain Scheduling For Improved PID Control

The present paper describes the development of a simple yet effective gain scheduling type fuzzy PID controller algorithm that can employ fuzzy adaptation to dynamically vary conventional PID controller gain(s). While one scheme can dynamically vary the reset rate only, an even improved scheme can effectively vary both proportional gain and reset rate of a PID controller simultaneously, employi...

Gain Scheduling for Networked Control System

Fuzzy Gain Scheduling for Magnetic Levitation Control

Magnetic levitation conveyor systems have many advantages compared with the general conveyor systems. Because of the non-contact structure, magnetic levitation systems offer frictionless, low noise, and the ability to operate in highly clean environment. In this environment, materials are sensitive to change location. When materials move to the desired position, the controller is required to be...

Gain Scheduling Control of Control Moment Gyroscope

This paper presents gain scheduling (GS) control of a Variable Speed Control Moment Gyroscope (VSCMG) based on sum of squares (SOS). Nonlinear motion equations of the VSCMG are complicated because they contain sine and cosine of angles of gimbals. The dynamics varies depending on an attitude of a spacecraft. In this study, the difficulty of control design of the VSCMG is solved by two methods. ...
