| Abstract | ||
| In this paper, the position control of frame work( disk-drive system) using proportional-derivative fuzzy sliding mode is proposed. First, the mathematical model of D.C motor and related components of the whole system is derived, model reduction technique is used to simplify the transfer function, then a designed classical controllers, like proportional-derivative(PD), linear quadratic regulator(LQR) are investigated, finally PD-fuzzy sliding mode control is derived with minimal rules for fuzzy is derived to compensate the uncertainties , which occur in the control, in which fuzzy logic control is used to compensate the chattering from applying the sliding mode control. The numerical validation results of the proposed scheme have presented good performance in transient and steady-state behavior (improving settling time and maximum overshoot) compared to the conventional controllers. So sliding mode fuzzy control is superior when compared with other controllers in terms of control performance. Various control schemes are then compared with each other. Simulations are carried out by using MATLAB. | ||
