利用基于线性矩阵不等式和鲁棒控制的多目标控制方法，研究了RTAC非线性控制设计的基准问题。该方法依赖于寻找一个公共的二次型李雅普诺夫函数来保证闭环系统的各种指标(稳定性、L 2-增益、命令输入输出峰值)。由此得到的输出反馈控制器是测量调度的；准确地说，其状态空间矩阵以非线性方式依赖于测量向量。我们通过各种模拟和预测的折衷曲线来评估我们设计的性能。(1998 John Wiley&Sons，Ltd.)
The RTAC nonlinear control design benchmark problem is addressed using a multi-objective control methodology based on linear matrix inequalities and robust control. The approach hinges on the search for a common quadratic Lyapunov function ensuring various specifications (stability, L 2 -gain, command input and output peak bounds) for the closed-loop system. The resulting output-feedback controller is measurement-scheduled; precisely, its state-space matrices depend on the measurement vector, in a nonlinear fashion. We evaluate the performance of our design with various simulations and predicted trade-off curves. ( 1998 John Wiley & Sons, Ltd.
