Iterative learning control based direct instantaneous torque control of switched reluctance motors

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
In this paper, iterative learning control (ILC) based direct instantaneous torque controller (DITC) for SRM is proposed. Direct torque control avoids the conversion of demanded motor torque into equivalent phase current references; which is non-trivial due to the coupled and non-linear torque, current and rotor position relationship.

Direct instantaneous torque control combined with torque sharing function strategy for switched reluctance drive

2012 Third International Conference on Intelligent Control and Information Processing, 2012
The inherent highly nonlinearity of switched reluctance motor not only makes it difficult to eliminate torque ripple with conventional average torque control techniques, but also restricts its application in the high-performance servo systems. A novel control strategy combing direct instantaneous torque control with the torque sharing function control ...

Direct instantaneous torque control of switched reluctance motor based on adaptive backstepping

2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014
Direct instantaneous torque control (DITC) is an efficient techinique of supressing torque ripple of switched reluctance motor (SRM). However, the performances of the conventional DITC with hysteresis torque control will be degraded due to limited sampling frequency in digital implementation.

Direct instantaneous torque control of a four-phase switched reluctance motor

2009 International Conference on Power Electronics and Drive Systems (PEDS), 2009
The paper presents an investigation on the direct instantaneous torque control (DITC) of a 1-hp four-phase 8/6 switched reluctance motor (SRM). In the proposed technique, the instantaneous phase torque was estimated in real-time using a pre-stored look-up table of measured static torque, T(i, λ), where phase current and phase flux linkage were input ...
