A Robust Variable Sampling Time BLDC Motor Control Design Based upon μ-Synthesis

The variable sampling rate system is encountered in many applications. When the speed information is derived from the position marks along the trajectory, one would have a speed dependent sampling rate system. The conventional fixed or multisampling rate system theory may not work in these cases bec...
