Abstract

The invention relates to a building method for an electric drive system hardware-in-the-loop simulation device. A converter, a motor and a position and speed sensor in a power transmission system are modeled through a hardware description language Verilog HDL and then are integrated into a field programmable gate array (FPGA) chip. The FPGA chip and an interface circuit form a virtual motor printed circuit board. The virtual motor printed circuit board is connected with an electric drive system controller printed circuit board to form the electric drive system hardware-in-the-loop simulation device. By the method, hardware-in-the-loop real-time simulation on an electric drive system can be performed and the quick development and product test of the electric drive system can be realized; moreover, the method has the characteristics of energy conservation, safety and low cost.

Description

technical field [0001] The invention relates to a hardware-in-the-loop real-time simulation technology, in particular to a construction method of an FPGA-based hardware-in-the-loop simulation device for an electric drive system. Background technique [0002] Real-time simulation technology is currently used in aerospace, military, and automotive industries. Compared with offline simulation technology, real-time simulation technology can realize the simulation of functions such as control interruption and delay, and is superior to offline simulation in terms of real-time and realistic approximation. At present, real-time simulation technology is divided into two categories: rapid control prototyping and hardware-in-the-loop. Rapid control prototyping technology uses virtual controllers and real control objects, and hardware-in-the-loop technology uses virtual control objects and real controllers. Constructing an FPGA-based hardware-in-the-loop simulation device for half-in-th...
