Development of Embedded Control based on Simulation
Abstract

Embedded control is in Power Electronic systems and electrical drives still more and more replacing the traditional electronic controls. The design of embedded controls usually takes place in a development environment programming the microprocessor, micro controller or DSP. Important in the design of embedded controls is the interaction with the controllable power electronics. Therefore a combination between the program development environment and the Power Electronics simulator is required. Ability to simulate the power converter circuit and at the same time to step with a debugger through the programming embedded control source code is hereby offered. In the paper such a development of embedded control with the help of a simulator is described.

Therefore a combination between the program development environment and the Power Electronics simulator is required to simulate the power converter circuit and at the same time to step with a debugger through the programming embedded control source code.

Integrated Control - Simulation Design Approach
Abstract

In this paper the modeling of motion control system with Variable Structure System (VSS) theory using Matlab/Simulink and Caspoc is elaborated. The control is modeled in Simulink, while the power converter is modeled in Caspoc. This has advantages on both sides. Powerful toolboxes existing for Simulink can be used and the power electronics can be modeled in detail in the dedicated power electronics and drives simulation program Caspoc. This approach and advantages of it are demonstrated on the motion control system. Experimental results of a DSPcontrolled single-degree-of- freedom motioncontrol system are presented too and compared with the simulation.

Integrated Control and Circuit Simulation for a Motion Control System
Abstract

In this paper the modelling of motion control system with Variable Structure System (VSS) theory using Matlab/Simulink and Caspoc is elaborated. The control is modeled in Simulink, while the power converter is modeled in Caspoc. This has advantages on both sides. Powerful toolboxes existing for Simulink can be used and the power electronics can be modeled in detail in the dedicated power electronics and drives simulation program Caspoc. The main contribution of this paper is the introduction of a powerful simulation tool, which can help in the keystep of most sliding mode designs, namely in the chattering free implementation. This approach and advantages of it are demonstrated on the motion control system. Experimental results of a DSP-controlled single-degree-of- freedom motion-control system are presented and compared with the simulation.
