Abstract :
In almost all industries the processes are nonlinear in nature. The nonlinear systems Preoccupied for study are the conical tank and spherical tank systems that is approximated to a first order equation. The control of level is carried out by using FOPIC technique. Fractional order calculus is a down order calculus having an area of arithmetic that has the derivative and integral from noninteger order. Fractional order PI controller (FOPIC) technique offers victory as a result of valuable methods in differentiation and integration and they offer additional flexibly in the controller design. This paper proposes the controller design for nonlinear systems using FOPIC. A relationship of this control technique with conventional Ziegler Nichols (ZNPI) controller and simulation be carried out by MATLAB simulink software.
