Markov Data-Based Reference Tracking of Tensegrity Morphing Airfoils
This work addresses control challenges for morphing airfoils in aerospace applications, but it appears incremental as it applies an existing data-based method to a new structural system.
The authors tackled the problem of reference tracking control for a tensegrity morphing airfoil by developing a data-based design that minimizes a quadratic cost function using only Markov parameters, achieving verification on a NACA 2412 airfoil with specified morphing targets.
This letter presents a data-based control design for reference tracking applications. This design finds the optimal control sequence, which minimizes a quadratic cost function consisting of tracking error and input increments over a finite interval [0,N]. The only information needed is the first N+1 Markov parameters of the system. This design is employed on a tensegrity morphing airfoil whose topology has been described in detail in this letter. A NACA 2412 airfoil with specified morphing targets is chosen to verify the developed design. The principle developed in this letter is also applicable to other structural control problems.
