Modeling and Velocity Tracking Control for Tape Drive System

A.A. Okubanjo, OK Oyetola, MO Osifeko, SO Adekomaya


The objectives of this paper are to formulate mathematical model for the tape drive system (TDS) by designing velocity tracking controller using physical laws. A Matlab function script and Simulink model were developed in Matlab and Simulink environment. The result of the study revealed that 7.07, 8 and 10 of koln values met the design goal and also resulted in optimal control performance with the following characteristics 7.31%,7.71% , 9.41% overshoot,1.07,1.08, 1.09 sec peak time , 0.385,0.346,0.281sec settling time,149,168 and 210 proportional gain, and 67.2,65.6, 62.3 phase margin respectively. While the responses at other values of koln resulted in an unsatisfactory performance. Based on simulation results and observations, it is evident that prediction of the performance of the controller depends on numerical value of koln .More so, larger values of koln lead to substantial increase in velocity variation resulting into worst prediction of the controller parameters.
