In this paper, a novel current tracking strategy for switched reluctance motor (SRM) is proposed, analyzed and verified. The relationship between pulse-width modulation (PWM) duty ratio and current variation in SRM over a cycle is investigated. The results demonstrate that an analytical resolution for calculating the duty ratio to achieve accurate current tracking is not possible because of the nonlinear inductance profile of SRM. Consequently, an iterative learning current control method is proposed, that can calculate the optimum duty ratio for tracking the reference current through periodical learning at different rotor positions in real-time. The learning gain for this proposed iterative learning-based current control algorithm is investigated and its upper limit is calculated by considering system convergence. In addition, an improved average current tracking strategy is presented in this paper. The numerical analysis performed in this paper clearly demonstrates the effectiveness of the proposed current control method for different speed and loading conditions. IX.

Growing concerns due to environmental impact of extensive fuel combustion by on-road transportation have emphasized the need for alternative solution to the on-board power generation. This paper proposes a novel method to generate electricity on board a vehicle by using local changes in pressure and shape of a pneumatic tire while vehicle is moving. Arrangement of a set of generators incorporated inside a vehicle's wheel is fully demonstrated in this paper. The paper proposes different generator configurations, and presents preliminary design and development of a linear permanent magnet generator using Finite Element Analysis.
