Abstract

The invention relates to the motor control field, and specifically to a motor control system. According to the motor control system provided by the invention, multiple phase windings that are not connected mutually of a controlled motor are controlled singly; the magnitude of current and the direction of each phase winding are adjusted to or maintained at a target value to enable the controlled motor to achieve a target characteristics without connecting the phase windings into a star structure or a closed loop, and without switches the phase windings between the star structure and the closed loop back and forth, therefore, the circuit is simplified, and the system stability is improved; compared with a method that the phase windings of the motor are connected into a specific topological structure in the prior art, the motor control method provided by the method is more flexible in motor control; and the motor control method can fully realize the circuit characteristics that can only be achieved by connecting the phase windings of the motor into the specific topological structure in the prior art, without changing the relative positions of the phase windings of the controlled motor, and without interconnecting of the phase windings.

Description

technical field [0001] The invention relates to the field of circuit control, in particular to a motor control system. Background technique [0002] In motor control, in view of the multi-phase windings of the controlled motor, it is often necessary to connect the multi-phase windings in the controlled motor to a special circuit topology (such as star structure, end-to-end closed Ring structure), so that the controlled motor can realize the corresponding characteristics, and different characteristics need to be realized by connecting the phase windings to different circuit topologies. In practical applications, in order to achieve different characteristics, the controlled motor will be multi Each phase winding is connected to the corresponding topology (such as star structure or closed ring structure), and when the demand for circuit characteristics is switched, it is necessary to switch the circuit connection mode of multiple loads; this requires additional Switching circu...
