PERFORMANCE ANALYSISOF LAG DOMINATED SYSTEM

Electronics and Instrumentation Engineering

Gravity Drained Tank System is a Bench mark system and the response for it has been already taken by using Conventional Controllers (LADRC, IMC , AMIGO, SIMC). Now in this project we are going to check and find the response of Gravity Drained Tank System by using Heuristic method (PSO).The conventional controllers contains proportional (P), integral (I), derivative (D), proportional -integral (PI), proportional -derivative (PD) and proportional-integral-derivative (PID) controllers. It is used in the forward path of the system. Conventional controllers are used in creativity, rules of thumb, selection and training of executives.The main advantage of adopting a heuristic approach is that it offers a quick solution, which is easy to understand and implement. Heuristic algorithms are practical, serving as fast and feasible short-term solutions to planning and scheduling problems. Heuristic problem solving techniques applied to training human decision makers and constructing heuristic computer programs. It is an optimization technique it is successfully used in many different engineering fields also. The method can be interpreted as a stochastic damped mass‐spring system. This analogy served us to show the PSO continuous model and to deduce a of PSO algorithms rising from the discretization of the PSO continuous model. So, we can analyse their respective first order and second order stability regions from the stochastic point of view.
