Abstract

In this paper, a new robust switching direct tracking adaptive control law (SDTACL) for a class of vector systems with unknown constant parameters and bounded disturbances is developed. The proposed SDTACL can overcome the drawbacks of dead-zone adaptive control and σ-modification adaptive control laws. Compared with switching-Σ adaptive control law (SSACL), it needs fewer free design parameters, analysis of SDTACL guarantees the controller gain will not drift to infinity in the presence of disturbance, and the matrix B is not required to be known
