Extended Exploration Grey Wolf Optimization, CFOA-Based Circuit Implementation of the sigr Function and Its Applications in Finite-Time Terminal Sliding Mode Control

The development of closed-loop circuit realizations chaotic synchronization and control is considered a promising aspect analog electronics. Therefore, this paper explores the use sigr function in implementation finite-time terminal sliding mode control. A CFOA-based proposed, whereby an Extended Exploration Grey Wolf Optimization method used to approximate non-integer powered transfer inside function. This configuration also allows for parallel which each coefficient can be independently elaborately tuned. Two second third order systems are presented demonstrate effectiveness developed achieve For system, applied stabilize chaos Holmes-Duffing system finite time, active stabilization modified Sprott-C presented. results show that has been satisfactorily achieved both cases, computer simulations implementations. Specifically, yielded maximum error 1.11%, while had 2.89%.
