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. …

Comparative Study of Torque Ripple Minimization of PMSM using PI and Proportional Resonant (PI-RES) Controller
Abstract: The minimization of speed ripple of the permanent magnet synchronous motors (PMSM) in low speed range becomes a major problem while applying the PMSM to refrigerant system. Earlier, an iterative learning controller was applied in conjunction with the conventional proportional integral (PI) speed controller to minimize the speed ripple. Here, a frequency variable resonance controller is applied in conjunction with the conventional proportional integral speed controller as a PI-RES controller, …
