In this paper modelling and analysis of the SRM torque characteristics including torque ripples are described. Optimal control strategy based on genetic algorithm (GA) to minimize torque ripple is proposed. The optimization criteria depend on choosing the exact current profile based on the optimal excitation parameters which govern the torque shape. The model and control are carried out on high...

This paper describes the robust optimal incremental motion control of a current  sensorless synchronous reluctance motor (SynRM), which can be specified by any desired speed profile. The control scheme is a combination of conventional linear quadratic (LQ) feedback control method and sliding mode control (SMC). A novel sliding switching surface is employed first, that makes the states of the Sy...

this paper gives a detailed analysis of direct torque control (dtc) strategy in a five-level drive and proposes a 24-sector switching table. the overvoltage problem due to high dv/dt is reduced compared to the 12-sector dtc. using all vectors leads to better flexibility and reduces speed oscillations. simulation and experimental results for a 3kva prototype confirm the proposed solutions. a tms...

Force/Torque sensing is very important for several automatic and industrial robotic applications. Basically, if precise control of the forces that arise from contact between tools and parts is required to successfully complete the automatic task, then a force/torque sensor is needed along with some force/torque control technique. In this paper we focus on force/torque sensing aspects applied to...

Induction motor drives using field oriented control (FOC) for torque and flux control have been used in high performance industrial applications instead of dc motors for many years. In FOC, torque and flux of an induction motor can be controlled independently by decoupling the stator current into its orthogonal components. The FOC method has achieved a quick torque response. But in order to ach...

background: mechanical torque limiting devices (mtlds) are necessary tools to control a peak torque and achieving target values of screw component of dental implants. due to probable effect of autoclaving and number of use on the accuracy of these devices, this study aimed to evaluate the effect of sterilization and number of use on the accuracy of friction-style mechanical torque limiting devi...

In order to improve the reliability and braking torque of aircraft electric braking system, this paper selected switched reluctance motor (SRM) as drive motor of electromechanical actuator, static torque data of SRM calculated by finite element analysis were used as training samples, then characteristics of torque-angle were obtained off-line by Generalized Regression Neural Network with partic...

Abstract: This paper presents a novel robust voltage-based control approach for tracking control of electrical manipulators by reducing the effects of uncertainties. The proposed control law is simple, fast response and robust with acceptable tracking error and without chattering problem. This approach is superior to torque-based control approaches due to considering the role of actuators. The ...
