In this paper, a new tracking differentiator is proposed based on the inverse hyperbolic tangent function. Due to the complexity of the tracking differentiator and the inaccuracy of tracking accuracy, accurate differential signals cannot be obtained. It is globally asymptotically stable, and its singularities are stable nodes by proper selection of parameters. The inverse hyperbolic tangent acceleration function has strong nonlinear characteristics, simple structure, less parameters and convenient adjustment. The simulation results show that NTTD is not only simple in structure form and relatively less in design parameters, but also has some advantages in tracking precision, response time and filtering ability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
