Instrumental variable method with optimal fractional differentiation order for continuous-time system identification

Abstract : this paper deals with continuous-time system identification using fractional differentiation models in a noisy output context. The simplified refined instrumental variable for continuous-time fractional systems (srivcf) is extended to optimize the commensurate order with a gradient-based method as the coosrivcf algorithm. Simulation analysis is used to demonstrate the performance of the proposed optimal instrumental variable scheme combined with order optimization.
