Abstract
It is useful for system engineers to initialize tuning parameters of adaptive control automatically. Adaptation gain and width of dead zone are tuning parameters of an estimation law using a dead zone. A control law has additional tuning parameters. This paper presents a new variable dead zone and a new automatic initialization method for adaptive control using a variable dead zone with a few tuning parameters that are determined by previously measured input and output data. The dead zone width in the estimation law is changed depending on the input signal by a rational function initialized using previously measured input and output signals. The control law used here is an H∞ control one referring to a complementary sensitivity function against unstructured uncertainty. We apply the proposed method to an electro-hydraulic servo system and verify the effects by experimentation.
