      this paper presents the design and implementation of robust real-time visual servoing control with an fpga-based image co-processor for a rotary inverted pendulum. the position of the pendulum is measured with a machine vision system. the pendulum used in the proposed system is much shorter than those used in published vision-based pendulum control system studies, which makes the system moredifficult to control. the image processing algorithms of the machine vision system are pipelined and implemented on a field programmable gate array (fpga) device to meet real-time constraints. to enhance robustness to model uncertainty and to attenuate disturbance and sensor nois , the design of the stabilizing controller is formulated as a problem of the mixed h2/h1 control, which is then solved using the linear matrix inequality (lmi) approach. the designed control law is implemented on a digital signal processor (dsp). the effectiveness of the controller and the fpga-based image co-processor is verified through simulation and experimental studies. the experimental results show that the designed system can robustly control an inverted pendulum in real-time.
