The Meaning of Innovate Experiment Teaching

At the modern higher education,training the practice ability of students is payed more and more attention,so the experiment teaching becomes a vital link of science and engineering education.But,as the rapidly increase of experiment items and students,conventional electric laboratory and experiment instrument can hardly satisfied with the demand, so that a hardware in the loop simulation experiment teaching concept has been focused by university construction.Simulation experiment teaching is a kind of virtual teaching system based on software technology, is digital and virtualization of various teaching laboratories,has several advantages:

1. Complementary of physical laboratory

2. Assist scientific research of university

3. Experiment Safety and easy to maintain

Solution based on StarSim HIL

ModelingTech HIL simulation platform aims at providing a experiment and simulation teaching platform which is advance and well-performance to undergraduate and graduate students in electrical-related majors.The innovative experimental base constructed based on the construction scheme can assist undergraduate and graduate students in teaching and scientific research experiments of power electronic technology, motor control, power system, new energy generation technology, relay protection and other related professional courses and design courses. Give consideration to theoretical teaching and scientific research practice, can carry out teaching principle verification, and can also carry out relevant scientific research projects.

Platform Structure

• Rapid Controller Prototype

Using ModelingTech MT 1030 RCP as the controller,which supports user defined algorithm compiled by Matlab/Simulink,can automatically accomplish code generation,and download to the RCP.Easy to run a new control algorithm,reduce the experiment time cost.

• Physical I/O interface Block

The simulation signal and PWM signal from HIL simulator and RCP controller are connect by physical I/O interface block.RCP collects the U/I signal which from HIL simulator and output PWM signal after compute to HIL simulator.

• HIL Real-time Simulator

Using ModelingTech MT 3200 HIL Real-Time simulator run the main electric circuit which can be instituted by Simulink.By using StarSim HIL host software can achieve model interfaces& physical interfaces signal mapping,then download and run the circuit model without compile.

Controller Host Software Introduction

StarSim RCP is a kind of host software of ModelingTech,cooperate with RCP device can conveniently accomplish control algorithm test.

1. Load control model:after the control program compiled,use Simulink>Code Generation to build a file which can be called in StarSim RCP.

2. IO mapping:user defined mode IO interface mapping with the RCP physical IO ports.

3. Model download and run: algorithm model can be downloaded in RCP device via host software StarSim RCP,and running as physical controller.at the same time,RCP will transmitted  the data up to host software,convenient to monitor and record,beside support adjust control configuration at running time,help user debug rapidly.

Simulator Software Instruction

StarSim HIL is a kind of configuration type software,support user defined circuit model download to simulator and one-key start simulation,help users accomplish simulation test rapidly.

StarSim HIL is convenient to use, only three steps can achieve offline model simulation to real-time model simulation.

1. Circuit Model download:StarSim HIL has strong compatibility,user defined circuit model can directly download to simulator.

2. IO mapping:user defined mode IO interface mapping with the HIL physical IO ports.

3. simulation running: down load circuit model directly without compile.circuit model can be download to simulator FPGA by StarSim HIL ,while the  circuit operation characteristics data transmitted to the controller,the data will also be transmitted to the host software interface,support online monitor and certainty control algorithm running status.
