Abstract

The invention discloses a method and equipment for realizing the rapid prototype designing of a PWM controller by combining a universal industrial personal computer and a DSP. According to the method and the equipment, a conventional xPC target technology is utilized, a large-step offline simulation model is converted into an actual control prototype, the actual control prototype is downloaded to the universal industrial personal computer for real-time running, a small-step control algorithm runs on the DSP, that is, a system-level control method is run by the universal industrial personal computer, a reference quantity signal of the DSP is output, the DSP receives the reference quantity signal from the universal industrial personal computer, and generates a control signal SPWM pulse signal corresponding to the reference quantity signal, control C codes are all automatically generated by a Matlab toolbox, and the control prototype is rapidly generated. All conventional rapid prototyping equipment produced by manufacturers is as expensive as a few hundred thousand yuan. However, the cost of hardware required by the method, such as the universal industrial personal computer, a data acquisition card and a DSP control board, is less than ten thousand yuan. Therefore, the method for realizing the rapid prototype designing of the PWM controller by combining the universal industrial personal computer and the DSP is a rapid prototyping solution with more advantages.

Description

technical field [0001] The invention relates to automatic industrial control technology, in particular to a method and equipment for realizing a rapid prototype of a PWM controller by combining a general industrial computer with a DSP. Background technique [0002] The power system is huge and complex, and the workload of system analysis and design is very large, which also limits the use of physical simulation methods for system research. In recent years, the rapid development of digital simulation technology has greatly improved the feasibility of modeling and simulation research on complex power systems. Digital simulation provides theoretical credibility and feasibility verification, but if it is converted into an actual usable device or program, additional design is required, and the designed equipment is directly used for electric power experiments, which has poor safety, high cost and low efficiency. At present, rapid prototyping design is to carry out product design...
