A Comparative Investigation of the Speed Regulation Capabilities of Electric Drives for Domestic and Agricultural Applications
Abstract: Performance enhancement of electric drives is an area of major concern in present day applications. In domestic sector and agricultural applications, conventional type of motors like Single Phase Induction Motors (SPIM) are still used, the dynamic performance and efficiency of which are poor. Replacing such motors with highly efficient Switched Reluctance Motor (SRM) will improve the performance as well as conserve the energy. This paper mainly focuses on the speed …

Drum-Boiler Dynamics and its Water Level Control
Abstract: Boilers used for continuous steam generation on large scale. Controlling aspect in boiler process is highly difficult as the system is complex and exhibit nonlinearity, the dynamics of boiler varies with load and multivariable dependent. The main cause of instability in boiler operation is due to the integration effect in it. In addition to that, boilers are normally used where there is sudden load variation without prior knowledge. In this …

Analysis of Three Tank Interacting System with Observer Based Controller
Abstract: The three tank interacting system is used as standard bench mark problem for various control strategies like fault tolerant control, robust control, optimal control and is also most widely used in process industries such as oil refineries, food process industries etc. Most of the literature accepted the fact that the interaction is the major problem in controlling the level of three tank system. In this paper, three tank interacting system …

Design And Implementation of Controllers for Quadruple Tank System
Abstract: Process industries have tightly integrated processes which are non-linear and have multiple manipulated and controlled variables. Level measurement plays an important role in many industries. In this paper, the level of the two lower tanks has to be controlled. Three different controllers have been designed and implemented by manipulating the motorised control valve. Conventional controllers may not perform well because of the variations in process dynamics and disturbances around them. …

Microgrid System Control Identification and Evaluation for Enhanced Dynamic Operation
Abstract: Networking the distributed generators (DG) in a microgrid system involves a large number of electronic components and filters. Small changes or drifts in operating conditions as well as disturbances at the point of common coupling can excite the associated eigenvalues giving rise to slowly growing instability in the system. This article considers the stability of a microgrid system consisting of a micro alternator, wind generator, photovoltaic (PV) system, fuel cell …

Faults Detection Techniques of Three Phase Induction Motor: A Review
Abstract: Induction motors are the most commonly used machines in industries. It is very robust, inexpensive and easy to maintain. Induction motors appear to various faults during their operation. Accurate fault identification is the prime industrial need to reduce breakdown, maintenance and revenue losses. Therefore, an early fault detection is needed for the protection of the motor against electrical and mechanical failures for continuing their operation safely. The main perspective of …
