Variable structure control applied to chemical processes with inverse response
TLDR
In this paper, a sliding mode controller based on a first-order plus-deadtime model of the system for controlling higher-order chemical processes with inverse response was proposed and evaluated via computer simulations.Abstract:
This article proposes the use of a sliding mode controller based on a first-order-plus-deadtime model of the system for controlling higher-order chemical processes with inverse response. The controller has a simple and fixed structure with a set of tuning equations as a function of the characteristic parameters of the first order-plus-deadtime model. The controller performance was judged via computer simulations using linear and nonlinear models of chemical processes with inverse response.read more

Sliding-Mode Robot Control With Exponential Reaching Law
TL;DR: A novel approach is proposed, which allows chattering reduction on control input while keeping high tracking performance of the controller in steady-state regime by designing a nonlinear reaching law by using an exponential function that dynamically adapts to the variations of the controlled system.
