GE-800 Series Motion Controller
.
Googol's inverted pendulum system is a nonlinear unstable system, an ideal experiment platform for teaching control theories and conducting various control experiments. Many abstract control concepts, such as the stability and the controllability of a control system, can all be shown visually through the inverted pendulum system. In addition to educational purposes, an inverted pendulum is also an excellent tool for researchers of modern control theories. Through continuous research,  new control methods haven been developed and then applied to high-tech industries such as aeronautical engineering and robotics.  
Googol's GE 800 Series motion controllers deliver precise, 8-axis DSP based control in a low-cost package, it was designed for point-to-point motion control. Owing to its capability of perfect positioning and velocity profile curves, it is used for quick and accurate positioning applications, and suitable for the equipments that adopt high-speed and high-precision point-to-point motion modes, such as PCB drilling machine, SMT, Bonding
machine, etc.
