example

[0104] Figure 4 with Figure 5 It is an application topology circuit of permanent magnet synchronous machine and induction motor built based on MATLAB / Simulink. The two different types of motor topology circuits are simulated in real time on the same FPGA module.

[0105] Image 6 It is the stator current waveform of the permanent magnet synchronous machine based on FPGA for real-time simulation using the method of this paper, where the number of pole pairs of the motor is 3, the speed of the motor is 1000r / s, and the torque Tm is 10N m; from the oscilloscope It can be seen that the motor current frequency is 50Hz, and the current amplitude is converted into an actual value of about 11A, which is basically consistent with the theoretical calculation result.

[0106] Figure 7 In order to use the method in this paper to simulate the stator current waveform of the induction motor in real time based on FPGA, the number of pole pairs of the motor is 2, the speed of the motor is ...

Abstract

The invention relates to a multi-type motor real-time simulation method and system based on an FPGA. The real-time simulation method comprises the following steps: 1, obtaining three-phase voltage of a motor port; 2, carrying out Park conversion on the three-phase voltage of the motor; 3, determining a type of the motor, and obtaining motor switching coefficients; 4, entering a corresponding variable differential calculation module according to different motor switching coefficients, and calculating a dq variable differential equation; 5, for the data obtained in the step 4, calculating, by a dq variable numerical integration module, a current value of a differential variable; 6, carrying out inverse Park transformation, and calculating current stator three-phase current. Compared with the prior art, the invention has the advantages that the consumption of FPGA resources is reduced, the real-time simulation realization difficulty of a complex multi-motor system is reduced, and the capability of a real-time simulation system for simulating other related power electronic systems is enhanced.

Description

technical field [0001] The invention relates to the technical field of real-time simulation of motor systems, in particular to an FPGA-based method and system for real-time simulation of multi-type motors. Background technique [0002] The motor is the key equipment to realize the mutual conversion of electrical energy and mechanical energy, and it is the key equipment in energy systems such as wind power generation and electric vehicles. The motor system controller is the core and key component of the motor device; the traditional development and testing method is to test the controller of the motor system directly on the physical system, but even if it is tested on a small power miniature physical system, there are still experimental High cost, more dangerous, difficult to achieve test automation and other challenges. [0003] The real-time simulator is a device that uses a mathematical model to simulate the actual system behavior on a real-time hardware platform. The rea...
