Abstract
This project includes Identification and Analysis, Creation of Mathematical model, Creation of Simulation model in Simulink environment and eventual control of the Hydraulic test rig with the help of MF634 multifunction I/O card. A large industry employs hundreds of controllers and each one of them must be tuned to be able to produce good control performance. Few of the tuning methods used in industries, in specific, the relay method is discussed. Subsequently, control program for automatic identification of Eigen frequency of the drive on the simulation model and then on the actual test rig is created. Using the critical parameters obtained, the controller parameters are calculated for the design of closed loop control.
