Abstract

The determination of parameters of controllers is an important problem in automatic control systems In this paper the Levenberg Marquardt LM Algorithm is used to effectively solve this problem with reasonable computational effort The Levenberg Marquardt LM Algorithm for optimization of three term PID controller parameters with dynamic model of pH neutralization process is presented The main goal is to show the merits of Levenberg Marquardt algorithm optimization and to determine its suitability in the area of control systems Lastly the application of this approach to the calculation of the parameters of PID controller shows that the Levenberg Marquardt LM algorithm has a better dynamic performance of pH neutralization process
