| Abstract: | Multiple fixed models and adaptive models are set up to cover the uncertainty of a SISO discrete time system with unknown and jumping parameters, and a multi model adaptive pole assignment controller is proposed by using a switching index function. On the premise that closed loop stability is guaranteed, this kind of multi model adaptive control (MMAC) can improve the transient response greatly. At the same time, localization method is introduced to reduce the computation burden of multi model algorithm without loss of accuracy. |
