本文研究的是具有外部干扰的线性系统的可控度（DOC）的测量。该文通过求解固定时间期望最小能量传递控制问题，提出了一种将初始条件视为随机向量的DOC新测度。由于这种新措施依赖于初始条件的统计信息而不是其估计值，因此更适合将所提出的措施应用于受控对象结构参数的设计和优化。此外，对 NREL（国家可再生能源实验室）CART3 风力涡轮机的模拟表明，所提出的措施与涡轮机参数（包括转子惯量和最佳叶尖速比）的关系与 MPPT 效率与涡轮机参数的关系一致。这表明该措施可用于指导风电机组结构参数的设计和优化。同时，还对质量-弹簧-阻尼器系统进行了仿真，以验证所提出的措施。
This paper is concerned with the measure of degree of controllability (DOC) for linear system with external disturbance. A new measure of DOC, in which the initial condition is regarded as a random vector, is proposed in this paper by solving the fixed-time expected minimum-energy transfer control problem. Since this new measure is dependent on the statistical information of initial condition rather than its estimated value, it is more suitable to apply the proposed measure in the design and optimization of the structural parameters of controlled plants. Furthermore, the simulations on the NREL (National Renewable Energy Laboratory) CART3 wind turbine demonstrate that the relation of the proposed measure to turbine parameters (including rotor inertia and optimum tip speed ratio) coincides with that of the MPPT efficiency to turbine parameters. This indicates that the proposed measure is applicable to guide the design and optimization of the structural parameters of wind turbines. Meanwhile, a mass-spring-damper system is also simulated to validate the proposed measure.
