The requirements for motion control were generated from the human eye features. The settling time and % overshoot were the desired features and design parameters. Based on desired features, values of and ωn were found. The root-locus technique was applied to the uncompensated and compensated system, the results were not satisfactory. The % overshoot was very high, and the steady-state error was also very high. The state feedback controller was applied to the system. The % overshoot was controlled successfully but the steady-state error was still very high. To reduce the steady-state error to zero the integral control was applied. The comparison of results is presented in tabular form in the last section.482021482021183193https://www.wseas.org/multimedia/journals/control/2021/a305103-1055.pdf10.37394/23203.2021.16.15https://www.wseas.org/multimedia/journals/control/2021/a305103-1055.pdfImran S.
