“Designing a phase lead, phase lag and phase lag-lead compensators using frequency response technique for performance evaluation of the hybrid stepper motor”
Journal Article

Abstract:- In this paper, modeling, control, simulation and performance analysis of the two-phase Hybrid Stepper Motor (HSM) with a phase lead, phase lag and phase lag-lead compensators using frequency-response technique (Bode plot) under the effect of external load for improving the transient and steady state response is presented. The applications of the two-phase Hybrid Stepper Motor (HSM) are increasing day by day. in order to have proper utilization of these motors and to control them effectively it is Important to have proper mathematical modeling of these motors. Similarly effective control these motors are also essential to have successful application of the devices across multiple domains. This paper handles both these important aspects. A mathematical model has been derived to represent a two-phase Hybrid Stepper Motor (HSM) model. The mathematical model was subjected to open loop and closed loop analysis to study the stability and performance. In this paper in order to validate the approach a MATLAB/SIMULINK model having a phase lead, phase lag and phase lead-lag compensators are constructed to control the modeled two-phase Hybrid Stepper Motor (HSM) under the effect of external disturbances for enhancement of static & dynamic response.
