The positive buoyancy diving autonomous vehicle combines the features of an Unmanned Surface Vessel (USV) and Autonomous Underwater Vehicle (AUV) for marine measurement monitoring. It can also be used to study reasonable efficient techniques underwater robots. In order optimization low power consumption high efficiency cruise motion vehicle, its dynamic modeling has been established. optimal cr...

Magnetic Levitation System (MLS) has become a current study in the field of engineering due to its advantages such as low energy consumption and minimum friction. MLSs are nonlinear unstable systems. Due complexity structure difficulty controls, many advanced control theories can be applied on these systems performance controllers evaluated. In this article, Proportional-Integral-Derivative (PI...

Particle swarm optimization (PSO) is an algorithm that simple and reliable to complete optimization. The balance between exploration exploitation of PSO searching characteristics maintained by inertia weight. Since this parameter has been introduced, there have several different strategies determine the weight during a train run. This paper describes method adjusting weights using fuzzy signatu...

In this paper, a new analytical method to find a near-optimal high gain controller for the non-minimum phase affine nonlinear systems is introduced. This controller is derived based on the closed form solution of the Hamilton-Jacobi-Bellman (HJB) equation associated with the cheap control problem. This methodology employs an algebraic equation with parametric coefficients for the systems with s...
