Abstract

This paper presents the design of Proportional Integral (PI) controller with Real Time Interface (RTI) to improve the dynamic response of digitally control dc to dc boost converter. The experiments were done under several load variations. DS1103 dSPACE RTI has been used as an interface controller between hardware and software by using MATLAB/Simulink model.

The inputs and outputs from the hardware were connected to dSPACE PPC Controller Board CP1103. By using dSPACE RTI, the response time of the system could be observed in real-time. The results, showed that boost converter was capable to operate in fast response with the variation of output load. The PI controller was capable to achieve faster transient response, stable and was more robust with digital control.
