Essential details：8272-582 Woodward APM Motor Control

Learning motor control to know their own foundation, if the student’s automatic control principle, modern control theory, motor science, power electronics related courses are learned very well, and now have not forgotten, then you can quickly get started, and after a period of practice will become a very good engineer. Let’s talk about how people with no basic foundation should learn, and also share my own experience and detours.

First of all, we must understand where the fundamental motor control is, the fundamental motor control is to control the current, how to send out the desired current, to achieve your purpose. Do not get a book to read when learning, reading is not meaningless, but in the case of no hands, many things in the book are not understood, the following is the recommended first book, to help you quickly get started, this book is called “Modern permanent magnet synchronous motor principle and MATLAB simulation”, the above things are very basic things, Follow the book a little bit to build matlab simulation, debug parameters, and you can see the waveform of each part, which is very helpful to understand the idea of motor control.

The purpose of motor control is to generate torque and maximize torque to improve motor performance. Therefore, how to ensure that the stator magnetic field and the rotor magnetic field intersect at all times is the core of motor control.

Since you want to control the Angle of the two magnetic fields, the first thing to do is to know the position of the magnetic field, the so-called rotor position – the reference. (This involves a very important Angle self-learning in motor control, which will be introduced in detail later)

After the rotor position is determined, the next step is to control the stator magnetic field position to 90° with the rotor magnetic field position. The stator magnetic field is achieved by controlling the three-phase alternating current (electrically generated magnetic), so the motor control is actually the control of the current.

As shown in the following figure, gray is the motor reference magnetic field position, pink is the stator magnetic field position, the Angle between the two is not 90°, so at this moment can produce a certain torque, but not the maximum.
