This paper presents a 5-D hyperchaotic Rikitake dynamo system with three positive
Lyapunov exponents which is derived by adding two state feedback controls to the famous 3 …

This paper proposes a eight-term 3-D polynomial chaotic system with three quadratic
nonlinearities and describes its properties. The maximal Lyapunov exponent (MLE) of the …

An adaptive fuzzy control method is developed to suppress chaos in the permanent magnet
synchronous motor drive system via backstep** technology. Fuzzy logic systems are used …

With system parameters falling into a certain area, the permanent magnet synchronous
motor (PMSM) is experiencing chaotic behavior which threatens the secure and stable …

Studies of nonlinear dynamical systems with many degrees of freedom show that the
behavior of these systems is significantly different as compared with the behavior of systems …

Chaos control means to design a controller that is able to mitigating or eliminating the chaos
behavior of nonlinear systems that experiencing such phenomenon. In this paper, a …

This paper studies an adaptive fuzzy control method combined with reduced-order observer
technology for the position tracking control of chaotic permanent magnet synchronous motor …

High power and high performance applications of permanent magnet synchronous motors
(PMSM) are increasing. PMSM models with accurate parameters are required for precise …

This paper addresses the robust stochastic finite-time and fixed-time chaos synchronization
of two permanent magnet synchronous motors (PMSMs) in noise environment. The novel …

Faults in engineering systems are difficult to avoid and may result in serious consequences.
Effective fault detection and diagnosis (FDD) can improve system reliability and avoid …
