This paper deals with design of various controllers such as Proportional Integral Derivative (PID) controller, Internal Model Controller(IMC) and transfer function controller by using Genetic Algorithm(GA) for a non-linear liquid conical tank system. Level control of a conical tank is a complex issue because of the nonlinear nature of the tank. For each stable operating point, a First Order Process...
The paper presents the proportional, integral and derivative (PID) digital controller based cascade control system and its experimental validation through three different testing scenarios namely, control action through Supervisory Control and Data Acquisition (SCADA), control action using Programmable Logic Controller (PLC) and interfacing of PLC with NI-OPC server. In this study, Micrologix-1200...
Parents are important for their children's development; they are the first order socialization agents, who, along with their teachers at school, are important for students' initial and fundamental learning affecting their personalities and lives. Therefore, we propose a joint action of both, teachers in school and parents as a coordinated and cooperated task related to educational work, so to become...
A high conversion ratio DC/DC converter with an active zero-voltage switching (ZVS) snubber circuit incorporated with maximum power point tracking (MPPT) techniques is presented in the paper. The MPPT controllers employ photovoltaic (PV) systems to make the converter output track the maximum PV output power. The active snubber circuit restricts the voltage stresses on the power switches. The simulation...
