Description: The PMSM FOC is made of several C modules, compatible with the free-of-charge IAR
EWARM KickStart edition toolchain version 4.42. It is used to quickly evaluate both the MCU
and the available tools. In addition, when used together with the STM32F103xx motor
control starter kit (STM3210B-MCKIT) and PM motor, a motor can be made to run in a very
short time. It also eliminates the need for time-consuming development of FOC and speed
regulation algorithms by providing ready-to-use functions that let the user concentrate on
the application layer. Moreover, it is possible to get rid of any speed sensor thanks to the
sensorless algorithm for rotor position reconstruction.-The PMSM FOC is made of several C modules, compatible with the free-of-charge IAREWARM KickStart edition toolchain version 4.42.

Description: An IEEE 802.15.4-based Wireless Sensor Network
is considered, and the relationship between the IEEE 802.15.4 topology formation mechanism and possible routing strategies at the network layer is studied. Two alternative routing schemes proposed in the framework of the ZigBee Alliance are analyzed.The first is the well-known Ad-hoc On demand Distance Vector
(AODV) routing protocol, which was designed for highly dynamic application scenarios in wireless ad-hoc networks. The second is
a tree-based routing scheme based on a hierarchical structure established among nodes during the network formation phase. This latter approach, referred to as HERA (HiErarchical Routing Algorithm) in the paper, routes packets from sensors to sink based on the parent-child relationships

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.
