Description: Paper about Induction motor drive based on direct torque control (DTC) which allows high dynamic performance to be obtained with very simple hysteresis control scheme. Direct control of the torque and flux is achieved by proper selection of inverter voltage space vector through a lookup table. In this paper apart from six sector look up
table used for classical DTC, a modified look up table, which also use six sectors but with different zones and a twelve sector table are presented. Platform: |

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: 该仿真模型是一种利用模糊控制器调节PWM信号占空比的异步电动机直接转矩控制的策略，即在传统异步电动机直接转矩控制的基础上，用模糊控制器代替传统DTC中的滞环比较器和空间电压矢量状态选择器来细分控制规则，最后控制逆变器的开关，以减小转矩和磁链脉动，从而改善交流异步电机伺服系统的动、静态品质，使整个系统具有较强的鲁棒性和自适应性。-A method of the stator resistance estimate which based on the fuzzy neural network was proposed and the motor speed is estimated by MRAS speed identification algorithm based on the stator voltage and the current that can be easily detected. Besides, a new design of fuzzy direct torque control system of induction motor was introduced in this paper, which based on strategy of modulating the duty cycle to decrease the torque and stator flux ripple. This design uses fuzzy control block to instead of the traditional space voltage vector selector to control the inverter switch which can improve the static and dynamic performances of AC asynchronous motors, which make the whole control system have strong robustness.

Description: Permanent magnet synchronous motors (PMSM) are appropriate for applications with load-independent speeds or synchronous operation with high accuracy under defined speed.
In this paper analysis the structure and equations of the PMSM, direct torque control (DTC) and voltage space vector process
then study model reference adaptive system (MRAS) estimators.
The PI controller uses from estimate speed feedback and do the speed sensorless control of PMSM based on DTC method with MRAS. The simulation results show that the speed of rotor

Description: modified direct torque control (DTC) scheme for
interior permanent magnet synchronous machine (IPMSM) is investigated
in this paper, which features in very low flux and torque
ripple and almost fixed switching frequency. It is based on the compensation
of the error flux linkage vector by means of space vector
modulation. Modeling and experimental results show that the flux
and torque ripples are greatly reduced when compared with those
of the basic DTC.With the new scheme, very short sampling time is
not essential. All the advantages of the basic DTC are still retained.
In addition, fixed switching frequency at different operating conditions
becomes possible.

Description: In this paper a new approach to direct torque control
(DTC) of induction motor drive is presented. In comparison with
the conventional DTC methods [1], [22] the inverter switching frequency
is constant and is dramatically increased, requiring neither
any increase of the sampling frequency, nor any high frequency
dither signal. The well-developed space vector modulation technique
is applied to inverter control in the proposed DTC-based
induction motor drive system, thereby dramatically reducing the
torque ripple and speed ripple. Platform: |

Description: sensorless induction motor drive is presented, in
which the principles of sliding-mode control, direct torque control
(DTC), and space-vector modulation are combined to ensure
high-performance operation, both in the steady state and under
transient conditions. Merits of the classic DTC transient behavior
are preserved, while the steady-state operation is significantly improved.
The torque and flux controllers, and motor state observer
are of the sliding-mode type. The inverter is directly controlled on
the basis of torque and flux errors, using space-vector pulsewidth
modulation. Computer simulations and experimental Platform: |
