In the past, implementation of active structural control strategies employing PC-based hardware has often been problematic, and there seems to be a need to improve the understanding of the issues associated with implementation of digital control, as well as to reduce the excessive computational times required for I/O processes and calculation of control forces. Recently developed hardware based on dedicated digital signal processing (DSP) chips has offered new possibilities for control algorithm implementation. This paper discusses digital control system concepts and specific practical aspects of digital control implementation including the use of supervision. Details regarding active structural control using the Texas Instruments TMS320C30 DSP chip and experimental verification of the hardware performance are given.
