Abstract :
A fast fine-positioning controller has been designed for a rotary-actuator-type magnetic-storage disk drive. The controller was designed using the LQG (linear quadratic Gaussian) methodology and has been implemented on a digital signal processor. It is shown that LQG design is a viable approach, and that various problems associated with the structural resonances of the actuator can be solved
