uad是由扰动模型导出的自适应控制分量,ϕ(x)包含干扰模型特征。 w为自适应扰动模型权向量。 控制器计算系统实际状态和估计状态之间的误差e(t)。然后它使用这个误差来实时调整w的值。控制器还利用e(t)实时更新估计模型的参数。增益Kx和Kr的取值由估计模型和参考模型的参数导出。 Estimator Model and Controller Gai...
The disclosure describes a system that includes a closed-loop reference module, an adaptation module, and a control module. The closed-loop reference module is configured to execute a reference model that represents operation of an engine and determine a reference control signal and a reference ...
TheModel Reference Adaptive Controllerblock implements discrete-time proportional-integral-derivative (PID) model reference adaptive control (MRAC). The three main components of an MRAC system are the reference model, the adjustment mechanism, and the controller. ...
See how an adaptive control method called model reference adaptive control (MRAC) can adapt in real time to variations and uncertainty in the system that is being controlled.

通过MRAC, 我们最后得到一个AS, \lim_{t\to\infty}e_m=0 , 这个AS 可没有说明它的性质比如上升时间,超调量之类。实际的系统,只有在matching condition 被满足后, e_m 收敛了,才会表现的和reference model 一模一样。 有趣的一点是,控制器 u=k_x(t) x+k_r(t) r ,没有能调参的系数,我们可以通过...
