Description: 本程序来自TI公司网站原程序,其功能是通过传统的矢量控制算法来实现对无速度传感器的异步电机的控制。程序的具体算法和介绍在软件压缩包有详细介绍！ -This system simulates a sensorless direct field oriented control of 3-phase induction motor with an "emulated" 3-phase induction motor model. The motor speed is controlled by using estimated speed as the speed feedback from the speed estimator of induction motor. The control strategy can be evaluated on TMS320C280x controllers without any power inverter and real induction motor. The system consisting of digital motor control modules is gradually built up until the speed control loop is finally closed. The incremental builds are included in the software to confidently build up the system. Based on TMS320C280x™ /TMS320F280x™ DSP controllers.

Description:
In this paper, new scheme of direct torque control of induction motor for
electric vehicles is proposed and the results of an investigation into suitable
torque control schemes are also presented. The electric vehicle drive consists
of rewound induction motors and a three-level IGBT inverter. The schemes
investigated are Field Oriented Control, Direct Torque Control (DTC), and
DTC using Space Vector Modulation. The results of Matlab - Simulink
simulations and a comparison between the control schemes are presented. It is
found that the DTC using Space Vector Modulation scheme is best for this
application. Platform: |

Description: This paper presents a new design of the torque and stator flux estimators for Direct
Torque control (DTC) for Field Programmable Gate Array (FPGA) implementation, which permit
very fast calculations. An alternative variable word-size approach in two’s complement fixedpoint
format is used for the implementation, in order to minimize calculation errors and the
hardware resource usage. The simulation results of DTC model in Matlab, which performed
double-precision calculations, are used as references to digital computations executed in FPGA
implementation. The Hardware-in-the-loop (HIL) method is used to verify the minimal error
between Matlab simulation and the experimental results, and thus the well-functionality of the
implemented estimators. Platform: |

需求。
-With the beginning of the AC induction motor speed control field dominance, speed control system for high-performance induction motor research has been widespread concern. Especially in the 1980s, Direct Torque Control (DTC) appeared, with its simple and efficient way to control and further improve the performance of asynchronous motor. However, the existence of traditional DTC will produce torque and torque ripple flux hysteresis width when making steady. Therefore, high-performance control requires a narrower hysteresis width, corresponding demanding inverter switching frequency. Where high power must be low switching losses and good torque control performance is difficult to meet the needs of traditional DTC. Platform: |

Description: 1Abstract—Today, linear induction motors spread out in the
field of transportation and many industrial fields such as
railway and electromagnetic launcher systems. Especially, high
efficiency control and fast dynamic response are demanded for
electromagnetic launcher systems and it’s well known that
direct torque control scheme provides fast dynamic response
for rotary induction motors. This paper describes Simulink
model of direct thrust controlled linear induction motor with
end effect for electromagnetic launcher system and presents a
simple and effective scheme for direct thrust control of a linear
induction motor. The Simulink model of single sided linear
induction motor with end effect developed to realize the direct
thrust control. To show the effectiveness of the improved
system, simulation results are presented using commercially
available software package Matlab/Simulink. Platform: |
