This article presents an antiwindup propor- tional-integral (PI) controller, using a saturating integrator, for single-input and single-output (SISO) stable nonlinear plant, whose steady-state input–output map is increasing. We prove that, under reasonable assumptions, there exists upper bound on the controller gain such that any constant reference input, corresponding equilibrium point of clos...

This paper proposes a new fast chargingstrategy for lithium-ion (Li-ion) batteries. The approach relies on an experimentally validated high-fidelity model describing battery electrochemical and thermal dynamics that determine the charging capability. Such high-dimensional nonlinear dynamic can be intractable to compute in real-time if it is fused with extended Kalman filter or unscented commonl...

Abstract— The main aim of this study was to control the nonlinear process using multi-model PI controller. A multi model is developed for conical tank and it is validated against the real time setup conical tank process. A Multi model based PI controller is also developed, and implemented with realtime setup, and their performances are compared with that of the conventional controller of real t...
