Abstract :
A fuzzy logic algorithm is applied to a bang-bang controller for a rigid disk drive. The algorithm has the two functions of ´trial seek´ and ´correction for uneven force´. The desired time of switching for bang-bang control is estimated using fuzzy logic: a method for correcting for actuator coil resistance due to temperature change is implemented. Experimental results illustrate the effectiveness of the approach.<>
