Design and Implementation of PID Controller for Second Order Plant and Comparison of its Performance with Fuzzy Logic based Controller
نویسندگان
چکیده
Controller designing for various day to day practical processes has been a challenging task for designers. Several issues such as stability, steady state error, effect of parameter variations and speed etc. must be considered for designing a controller. In this communication, an arbitrarily underdamped second order plant is implemented which has highly oscillatory response. Then a PID controller is designed for improving the system stability. Further a fuzzy logic Controller is also designed for the same second order system and its result with PID controller is compared. Simulation of Fuzzy logic controller is done on MATLAB and for PID controller ORCAD PSPICE is used. Also hardware implementation of the system with PID controller is done using Op-Amp 741 IC.

A New Intelligent Controller for Parallel DC/DC Converters
In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...
