The paper presents a hall-effect sensor-assisted nonlinear observer-based solution for position locking of a surfacemounted permanent magnet synchronous motor (SMPMSM) propeller drive in drone applications. The purpose of the position locking is to ensure a fixed motor position at the landing instant to avoid mechanical damage to the propeller. To evaluate the proposed solution, the position locking sequence of the motor drive is studied for two cases, implemented with two different state machines. The first case is relying on an encoder to provide the position feedback signal and serves as a reference for assessing the performance of the proposed solution based on the position estimate from the hall-effect sensor-assisted nonlinear observer. Experimental results show how the proposed solution can provide sufficient performance of position locking without the encoder.

“…Recently, with the strengthen of consciousness about energy conservation and environmental protection, high performance and energy-saving industrial sewing machines are developed promptly and used widely. Contrast induction motor, permanent magnet synchronous motor is going with higher energy-efficient, lower inertia, more flexible design, more simple control system and wider speed regulation [1,3] . With these inherent advantages, nowadays more designers tend to drive industrial sewing machines by PMSM control systems [2] .…”

Along with the progress of intelligent control and robot technology, machine arms, which are not so easy to be effected by the environment, easy operated, have taken place of human in more and more field. The motor used in the joint of machine arm is very important and has more influence on the system. The choice of the motor and relative method of control has more or less effect on the cost, operating precision and the reliable of the arm. Among all the motors that can be used in the joints, Brushless DC motor (BLDCM), which has advantages as low cost, light quality and high reliable etc., has taken more and more attentions. In this paper, we analyze the characters of one kind of the high-energy density designed BLDCM in robot according to environment and its structures.
