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
estimates with high precision and torque response is considerably fast.

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

Description: This paper presents the sensorless direct torque
control (DTC) technique for five-phase interior permanent
magnet (IPM) motors. By using the introduced technique fast
torque response with low ripple in the stator flux and torque of
the five-phase interior permanent magnet motor can be achieved.
Having thirty-two space voltage vectors provides great flexibility
in selecting the inverter switching states. Therefore, the stator
flux and torque can be more precisely adjusted. Position
information and speed are being estimated based on the position
of the stator flux linkages. The mathematical model of the fivephase
interior permanent magnet motor is first derived. Later,
the speed sensorless direct torque control method of the fivephase
IPM is introduced. A five phase interior permanent
magnet motor and five leg IGBT based inverter were designed
and fabricated in the laboratory. The control method is
implemented on a TMS320C32 digital signal processor board.

Description: Introducing the rank-weight method into the
basic ant colony optimization (ACO), we use the modified
ACO to optimize the weights and thresholds value of neural
networks (NN). And when the BPNN is being trained, this
method can solve the disadvantages of running into the
minimum easily, and enhance the convergence speed. So we get
a heuristic method, which is good at time efficiency and
derivation efficiency that is ACOrw-BP. Then this method was
used to identify the speed of the motor in direct toque control
(DTC).The results of the simulation showed that: the modified
ACOrw-BP neural network not only has the ability of mapping
widely, but also enhancing the operation efficiency obviously.
The speed of the motor can be identified accurately by this
method, and the result is good. So, it implements the direct
toque control of speed sensorless.
