Variable Speed Drive Applications Performing Effectively with ANN Technique

Abstract

Abstract The preservation of variable speed drives at ripple and harmonic less output functions at different applications application is vital. The variable speed drive applications involve the use of different converter topologies, which makes the system to reduced efficiency and leads to reduced performance. A modern development in power electronic technologies makes the proficient control schemes to obtain a ripple and harmonic less variable speed drives. The proper selection and arrangement of control scheme may enhance the performance and efficiency of the speed drives. Various control topologies are suggested elsewhere in the world to obtain the effective performance of the variable speed drive applications. Each control strategy may have its own merits and demerits compared to other techniques. Artificial Neural Network (ANN) based technique is made a significant importance in recent years and showing enhanced performance variation compared to other existing control strategies. This paper presents the design of 15 level inverter circuits and functioned using artificial neural network (ANN) control technique to obtain the effective performance for various speed drive applications. Also, this paper presents the space vector pulse width modulation (SVPWM) control technique and fuzzy logic control techniques to same 15 level multilevel inverter circuit. The results of three, ANN, SVPWM and fuzzy logic techniques are compared and made suggestions on suitable effective control technique for variable speed drive applications.
