For the general second-order quasi-linear system model describing the six typical flight vehicle control problems proposed in the part one of the paper, a direct parametric design approach is introduced, which designs a quasi-linear state feedback control law that makes the closed-loop system a constant second-order one with a desired closed-loop eigenstructure. Furthermore, all the design degrees of freedom are provided, which can be comprehensively optimized to realize the multi-objective designs of the system, and the design requirements on the desired eigenvector structures, disturbance attenuation and insensitive closed-loop eignenvlaues are treated as examples. Finally, the development prospect of the quasi-linear system theory is outlined.
