Due to factors such as uneven guide rails and airflow disturbance in the hoistway, high-speed elevators may experience significant vibrations during operation. This paper proposes an optimized fractional-order PID (FOPID) method suppress of elevators. First, accurate horizontal vibration model is established for elevator car, which car frame body are separate. Then, taking control cost system p...

Robust stability is a major concern for real-world control applications. Realization of optimal robust requires stabilization scheme, which ensures that the system stable and presents performance predefined range perturbations. This study presented an approach closed-loop fractional order proportional integral derivative (FOPID) systems with interval parametric uncertainty uncertain time delay....

A pneumatic cylinder system is believed to be extremely nonlinear and sensitive nonlinearities, which makes it challenging establish precise position control of the actuator. The current research aimed at reducing overshoot in response a double-acting actuator, namely, IPA positioning system’s reaction time. was modeled using an autoregressive with exogenous input (ARX) model structure, strateg...

In this article, a fractional-order proportional-integral-differential (FOPID) controller and its modified structure, called MFOPID controller, are presented. To guarantee optimal system performance, the gains of proposed FOPID controllers well-tuned, employing Jellyfish Search Optimizer (JSO), novel highly effective bioinspired metaheuristic approach. The assessed in hybrid with two domains, w...

Abstract Closed-loop DC Micro-Grid containing sustainable power sources, stockpiling components and burdens are introduced. The regulators for helping the control of mico-grid numerous in power-frameworks, yet most normally utilized one is PI regulator. Aside from there are, an entire bundle independent hybrid that can serve significantly better compared to microgrid framework relevance’s. syst...

The hypersonic vehicle model is characterized by strong coupling, nonlinearity, and acute changes of aerodynamic parameters, which are challenging for control system design. This study investigates a novel compound scheme that combines the advantages Fractional-Order Proportional-Integral-Derivative (FOPID) controller Linear Active Disturbance Rejection Control (LADRC) reentry flight vehicles w...

Nano-satellites are very popular among researchers today because they more affordable and easier to use than most large satellites. The system performance on nano-satellites needs be improved for better by using fractional order PID (FOPID) controllers which have never been tested unstable systems nano-satellite objects. controller development produces two power parameters called the FOPID cont...
