This paper describes the practical implementation of two well known robust control strategies over a non-linear magnetic levitation system for controlling the coil current so as to achieve the desired position. In order to make the controller robust and practically implementable, higher order sliding modes (HOSM) technique is used. Two second order sliding modes (SOSM) schemes are applied on the actual...
Sun tracking system is used for efficiency improvement. To solve problems that presents in existing solar-tracking system such as it cannot work without electricity, this report puts forward an automatic sun tracker driven by differential pressure Controlled system. Main work of this system is to collect the maximum solar energy and convert it into electricity. Due to gravity it turns the tracker,...
This paper presents a robust control of magnetic levitation system. A Second Order Sliding Mode Control (SOSMC) based on Super-wising Algorithm (STA) has been given. The control is smooth, so as to implement practically. The proposed sliding surface is a function of output error. The detailed closed loop stability analysis has been given. The proposed method is validated in simulation as well as implemented...
Active power filters have become very popular in AC power networks for reducing harmonic pollution and for reactive power compensation. The network containing non linear loads like power converters are provided with either shunt type or series type active power filter for improving THD. It also improves voltage regulation and flicker unbalance. The instantaneous power theory also known as p-q theory...
Here active fault tolerant control is proposed for Autonomous Underwater Vehicle (AUV). When fault occurs system performance degrades and is used as reference model to design reconfigurable controller to prevent saturation of actuator in AUV. The dynamics of AUV will follow new reference model after fault occurs. The proposed method is simulated using PID controller on REMUS-100 AUV model under limiting...
Control and modeling of nonlinear systems like Autonomous Underwater Vehicle (AUV) is a challenge for researchers. Here the modeling and controller scheme designed is based on fractional order system. In this article Fractional order proportional integral derivative (FOPID) controller is designed and applied to fractional order depth and steering systems of AUV and it is compared with classical integer...
Autonomous underwater vehicle (AUV) system is complex and highly nonlinear, the controller design for AUV is always a crucial task. Improving the performance of AUV in such applications as seafloor mapping, oil and gas exploration and defense requires improving the vehicle's maneuvering precision. These goals can be achieved through the improvement of the vehicle control system. This paper presents...
Supercapacitors (SC) / Electro Chemical Double Layer Capacitor (EDLC) is yet to experience widespread use. Recently, advances have been made in improving both energy and power density. Due to their limited power and energy capabilities, they saw use in applications such as memory backups. New applications in the area of FCV, EV, EHV, space, military, automotive subsystems and industrial automation...
