In recent years, fast development of unmanned aerial vehicle (uav), is in full swing, from low-end to high-end of unmanned aerial vehicle (uav) on the market of all kinds, model aircraft unmanned aerial vehicle (uav) is no longer just a few professional players and enthusiasts who can finish, have more kinds of commercial unmanned aerial vehicle (uav) came to the front of people, to our life and production, its performance and price is more and more adapted to many places and people. Whether its performance is superior not only rely on a set of reliable flight control system, which composed of electrically controlled stability and reliability of the power system is an indispensable part of.

electrically controlled
electrically controlled full name is the electronic governor (电子调速,ESC), main effect is in accordance with the relevant control signals to control the speed of the machine. According to different types of motor, divided into brush electric harmonic brushless electric adjustable. With the vigorously development of brushless motor, brushless motor volume under the same power than a smaller brush motor and brushless motor control system is gradually mature and perfect, the brushless electric adjustable gradually occupy the mainstream in the market. Have a wide range of applications in the motor industry.
today dongguan model aircraft brushless electric adjustable many industries has been widely used, such as electrical modulation on medical equipment, electric car electrical modulation on the electrically controlled, household appliances, special special electric fan, and now is the most widely used electric toy model. And electrically controlled toy model types and divided into several categories according to the model, model aircraft, car model, model, etc. , including its performance requirements are also different.

control mode
because at this stage the model aircraft electrical modulation are available in the market to drive the brushless dc motor is given priority to, the commonly used brushless dc motor control method has two kinds: one is a square wave control, is a kind of vector frequency conversion control. Due to the square wave control mode simple and direct, hardware structure is relatively simple, the cost is relatively low. But because of its control characteristics, there are still large torque pulse, start is not stable, run large noise and other issues. Due to previous years industry demand is not high, make electrical modulation control method rect control primarily. But with the development of technology, and semiconductor devices constantly updated, some high-performance MCU and driving device, costs less and less, makes the high performance motor control method applied in model aircraft electrical modulation. A lot of model aircraft manufacturers also began to try to run more superior performance vector frequency conversion technology to model aircraft in the motor control. And easyarm microcontroller years of accumulation motor vector frequency conversion control technology (船Used in model aircraft electric adjustment, and form a complete set of application solutions, including the overall design scheme of hardware circuit and software design. And after a series of performance tests, proved FOC control method compared with the traditional way of square wave control, start smooth, small torque pulse, there is no running noise and sensitive response speed and other advantages.
