An Experimental Demonstration of Npid Control with Application to Optical Storage Drives
نویسندگان
چکیده
The application of NPID, or nonlinear PID, control is demonstrated experimentally on an optical storage playback device (CD drive) for automotive applications. The nonlinear design aims at improved shock suppression under equal noise response. This is done by introducing variable controller gains. Namely under large levels of low-frequency vibration, the controller gains are increased as to improve low-frequency sensitivity. High-frequency sensitivity, however, remains unaltered as to keep a low-level noise response. Copyright c © 2005 IFAC

Nonlinear PID Control with Partial State Knowledge: Damping without Derivatives
Nonlinear PID (NPID) control is implemented by allowing the controller gains to vary as a function of system state. NPID control has been previously described and implemented, and recently a constructive Lyapunov stability proof has been given. The controllers arising with the constructive Lyapunov method will in general depend on knowledge of the full state vector. In the present work, NPID co...
متن کاملLabVIEW implementation of an enhanced nonlinear PID controller based on harmony search for one-stage servomechanism system
This paper presents a practical implementation for a new formula of nonlinear PID (NPID) control. The purpose of the controller is to accurately trace a preselected position reference of one stage servomechanism system. The possibility of developing a transfer function model for experimental setup is elusive because of the lack of system data. So, the identified model has been developed via gat...
