查询词典 convex

Therefore, a design scheme via LMI approach is presented in order to improve the system robustness. By using the LMI approach, the attitude controller design is reduced to a convex optimization problem based on the polytopic system. Since there are some degrees of freedom when solving the LMI, it is available to use this kind of freedom to achieve multi-objective control within this framework.
