WebIn this paper we discuss an interesting problem encountered in control engineering called the attitude control problem. This problem attracted our interest because of recent work … WebMay 18, 2004 · We consider the attitude control problem augmented with an arbitrary number of nonconvex quadratic constraints. By utilizing the implicit magnitude constraint of the state vector (i.e., quaternion), we are able to reduce this problem to a convex quadratically constrained quadratic program or a semidefinite program. This result leads …
