Simulating real DSP code using a DLL, application to a 3-level VSI SVC
Abstract
The present paper addresses the use of a Windows™ DLL to simulate the real code of a DSP for faster development time and advanced testing, especially in high power systems. The development of power system control usually starts with simulations and the development of the control is done with the simulation tool native blocs. Once the control is validated in simulation it is usually C coded into a DSP and real test can be performed. The present paper introduces a way of simulating the real DSP code to fill the gap between simulation and reality. By generating a DLL, the DSP C Code can be called by the simulation tool (in our case SIMSEN). The power part is 'analogically' simulated with a small integration step, and the DLL is called 'digitally' at a given sampling time. A 3-level VSI SVC is used as a guideline to illustrate the concepts presented.

Simulation
A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games.
Control system
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines. The control systems are designed via control engineering process. For continuously modulated control, a feedback controller is used to automatically control a process or operation.
Training simulation
In business, training simulation is a virtual medium through which various types of skills can be acquired. Training simulations can be used in a variety of genres; however they are most commonly used in corporate situations to improve business awareness and management skills. They are also common in academic environments as an integrated part of a business or management course. The word simulation implies an imitation of a real-life process, usually via a computer or other technological device, in order to provide a lifelike experience.
