In this project the dynamics in the open electro hydraulic servo control model have been replaced by first order transfer functions. This simplified model allows much faster calculations and thus, it is not necessary to go into its dynamics. Thus, lumped transfer function models are derived from simple electro hydraulic servo control model. Secondly a PID controller attempts to correct the error between a measured process variable and a desired set point by calculating and then outputting a corrective action that can adjust the process accordingly.
