摘要：AbstractBased on factorization of high frequency gain (HFG) matrix Kp, a novel fractional order composite model reference adaptive control (FO-CMRAC) is investigated for a class of fractional order MIMO systems. By introducingKp= SDU, the stringent symmetry assumption related with the plant high frequency gain matrix is removed. Besides, with the aid of fractional order tracking differentiator (FOTD), the parameter estimation errors is obtained to construct the fractional order parameter updating laws, which can improve the tracking performance. In addition, both the convergence of closed-loop control systems and parameters estimation are proven by indirect Lyapunov approach. Finally, two numerical examples are presented to illustrate the effectiveness of the proposed approach.
