A Study on the Speed Control of Induction Motor Using Modified SVPWM Control Method
허재정 한국수산해양교육학회 2020 水産海洋敎育硏究 Vol.32 No.2
This paper compares and analyzes the direct torque control method, which is widely used for induction motor speed control, and the indirect vector control method, which uses the modified SVPWM method, which has much lower computational power than the general SVPWM method. The modified SVPWM shows similar performance in the high speed range compared to the direct torque control method in speed, torque, input current, and load current control performance, but it shows remarkably superior performance in the low speed range. The computer simulations using the PISM program confirmed the characteristics of the control methods and verified their effectiveness.
A Study on Speed Control Method of Propulsion Motor for Small Ships with AFE Converter
허재정 한국수산해양교육학회 2020 水産海洋敎育硏究 Vol.32 No.1
Research of electric propulsion system have been conducted to minimize the occurrence of marine environmental pollution and maintenance costs in small ships such as coastal passenger ships, cruise ships and fishing boats. Speed control methods induction motor that are widely used in large electric propulsion ships has low control characteristics in the low speed range, and therefore, the performance of the steering is very deteriorated in ships with a large number of the entry and departure of port. Therefore, in this paper, the vector control algorithm with the AFE rectifier is applied to induction motor and speed control performance at low speed range has been improved. and it was verified through computer simulation using PISM program.
