Modified robust optimal adaptive control for flight environment simulation system with heat transfer uncertainty

Multivariable Bi-Objective Optimal Modification Adaptive Control for Turbofan Engine With Matched Uncertainty and Slow Actuator Dynamics

“…Then, we choose the adaptive control structure for the input signal of actuator as [14] There exist two ideal control gain matrices K *…”

“…Lemma 3 [14]: For any square real matrix ∈ R n×n , it can be decomposed into a symmetric part N and anti-symmetric part O as…”

“…Recently, with the study and development of adaptive control theory, adaptive control has been widely applied in many important engineering areas, such as aircraft engine [7]- [9], industrial [10]- [12], UAVs [13], altitude ground test facilities [14], etc. In addition, many MRAC approaches have been proposed to provide robustness for system with uncertainty [14], [15].…”

To enhance the robustness of the conventional MRAC, several robust modification approaches such as adaptive loop recovery modification [16], dead-zone modification [17], and Optimal Control Modification (OCM) [18] have been considered.…”

“…Nguyen used the OCM method to improve control effectiveness of systems with both matched and control input uncertainty [23]. The OCM method is used to address robust control of flight environment simulation system with disturbance and large heat transfer uncertainty [14]. For system with unknown control input matrix , the OCM method cannot obtain the adaptive law.…”
