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...

A new NPID (Nonlinear Proportional-IntegralDifferential) control algorithm is applied to a class of truck ABS (Anti-lock Brake System) problems. The NPID algorithm combines the advantages of robust control and easy tuning. Simulation results at various situations using TruckSim show that NPID controller has shorter stopping distance and better velocity performance than the conventional PID cont...

A nonlinear PID (NPID) controller for a class of linear plants with output feedback is studied. The controller gains are modulated by the control error and error rate to yield a closed-loop system for improved disturbance rejection. An optimization problem involving constraints written as linear matrix inequalities (LMIs) is solved to compute the controller parameters. A hard disk drive (HDD) c...

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...

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 imp...

We consider the problem of finding optimal, robust stabilization of linear systems within a family of nonlinear feedback laws. Investigation of the efficiency of full-state and partial-state based so called NPID feedback schemes proposed for stabilization of systems in robotics applications has provided the motivation for our work. We prove that for a given quadratic Lyapunov function and a giv...
