Shaking tables are frequently used for dynamical testing. To produce correct results, a shaking table must be able to move according to the desired acceleration signal in a wide range of frequencies. Accelerometers and displacement sensors are used for controlling input, and, in some cases, they have been used for preventing drift. However, at low frequencies, accelerometers do not always provide accurate values. We developed a shaking-table control system that uses a sensor-fusion control function. In this paper, we present the design scheme for our control system and the results of a simulation that validate it.
