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...
For the boiler-turbine unit in power systems, a coordinated control structure plays crucial role maintaining balance supply and demand of energy, reducing pollutant emissions optimizing energy efficiency. The matching requirements turbine boiler, wide range load changes, cooperative operation many devices system pose challenges to designing for boiler system, thus making design difficult task. ...
A new method for designing PID Controllers using Bode's ideal transfer function and constrained Particle Swarm Optimization (PSO) is proposed in this paper. Bode's ideal transfer function is introduced using fractional calculus and Carlsson's approximation is used for converting the transfer function from fractional to integer domain. The PID controller is designed by minimizing ...
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....
