This paper describes the micro-computer feedback contol system for active modular panel systems in order to insulate floor impact noise. We develop a micro-computer system equipped with Renesas SH3-DSP processesor. The micro-computer system is composed of two boards: CPU board and analog I/O board. Renesas SH3-DSP processor has a function of digital signal processor which performs high-speed calculation of fixed-point number. Because we use Matlab software in order to design robust feedback controllers, each entry of controller matrices is double-precision floating-point number. Rounded errors occur when these matrices are installed into the micro-computer system. First we show the construction of the developed micro-computer system and the block diagrams of the robust feedback system. Next we conduct the control experiments of with twelve panels and discuss about the effects of rounded errors.
