Induction Motor DTC Performance Improvement by Reducing Flux and Torque Ripples in Low Speed

Torque Ripples Minimization on Dtc Controlled Induction Motor with Adaptive Bandwidth Approach

Field oriented control (FOC) and direct torque control (DTC), also called vector control, are most famous control methods in high-performance motor applications. If we want to specify the basic handicaps of both methods: the FOC has parameter dependence while the DTC has high torque ripples. This paper proposes a new adaptive bandwidth approach to reduce torque ripples in DTC controlled inducti...

Improved DTC Algorithms for Reducing Torque and Flux Ripples of PMSM Based on Fuzzy Logic and PWM Techniques

investigation on the flux-based torque-ripple behavior in dtc based induction motor drives

the efficiency of induction motors decreases at light loads. efficiency optimizer control systemsadjust the motor flux value to achieve the best efficiency in a wide range of load variations. reduced fluxoperation has some other benefits such as power factor improvement and torque ripple reduction. the latter isan important issue in a direct torque controlled induction motor drive. in this pape...

Speed and Torque Control of an Induction Motor with Ann Based Dtc

Due to advantages such as fast dynamic response, simple and robust control structure, direct torque control (DTC) is commonly used method in high performance control method for induction motors. Despite mentioned advantages, there are some chronically disadvantages with this method like high torque and current ripples, variable switching behaviour and control problems at low speed rates. On the...
