The in-situ stress is a crucial parameter in rock engineering. CSIRO in-situ stress measurements are one of the four suggested direct measurement methods and have been widely used worldwide. With the development of exploration and excavation in deep earth, temperature disturbances during overcoring and the nonlinear behavior of rock under high stress levels increase the error of CSIRO in-situ stress...
Present work shows the merits of space vector modulation direct torque control(SVM-DTC) over the conventional direct torque control(conventional DTC). SVM-DTC technique is helpful in solving the basic issues of torque ripple and variable swithing frequency present in the conventional DTC. In order to get the reference voltage vector which is necessary for the SVM-DTC, this paper describes a method...
In the paper, a new approach to direct torque control (DTC) of induction motor drive based on dual-fuzzy space vector modulation (SVM) technology is proposed. In comparison with the conventional direct torque control using space vector modulation technology (SVM-DTC) method, two fuzzy controllers are used to generate the two components of reference voltage vector instead of two PI controllers. With...
