In this paper, an on-board integrated battery charger based on central-tapped winding switched reluctance motor of electric vehicle is presented. All the components used for driving mode are employed in the charging process, and there is no need for hardware reconfiguration between charging and driving modes of operation. The solution can be connected directly to single-phase grid to perform charging...
A fault tolerant position estimation for Switched Reluctance Motor (SRM) is proposed in the paper based on relationship between inductance and rotor position. First, the particular position signal is obtained by comparing the real-time flux linkage with the particular position flux linkage, the position is estimated by the particular position signal. Second, the delay method is used based on inter-phase...
Nonlinear inductance profiles of switched reluctance motor (SRM) cause the complicated design of controllers, which leads to SRMs have not been widely applied in industries fileds. A traditional PI controller with fixed gain is easy to realize the control of SRMs. It can not provide good control performance over the whole range of speed regulation. To solve the problem, an adaptive PI controller of...
In this paper, a control strategy for switched reluctance motor(SRM) based variable speed drives is proposed. The phase inductance profile for an SRM being nonlinear, a small signal model based method is applied in a restricted way to design and then implement the controllers based on a linearised model. Two control loops — a Pi-controller based speed loop and and a hysteresis controller current loop...
A new continuous sliding mode control method has been developed by combining Variable structure system (VSS)and Lyapunov design. It possesses all the good properties of the sliding mode control and avoids the unnecessary discontinuity of the control input, thus eliminating chattering. This paper focus on the application of continuous sliding mode controller in speed regulation system of switched reluctance...
Soft Magnetic Composite (SMC) material is formed by surface-insulated iron powder particles, generating unique properties like magnetic and thermal isotropy, and very low eddy current loss. This paper delineates the key aspects of soft magnetic composite (SMC) material application in Switched Reluctance Motor(SRM), through dynamic magnetic characterization using Switched Reluctance Design and Simulation...
A novel scheme for nonlinear predictive control of switched reluctance motor(SRM) based on target state equations (TSEs) is proposed in this paper. According to the nonlinear model of SRM, the offsets of the torque and angular speed of SRM is defined as TSEs by applying the nonlinear control theory. Based on TSEs and predictive control theory, a nonlinear predictive control for SRM control system...
