摘要

本文提出了一种基于模型控制器的麻醉控制方法。考虑用异丙酚全身麻醉。该方案试图利用基于模型的控制器的优点来提高麻醉的控制性能。所提出的控制器是基于两个控制动作的应用。首先,应用从逆动力学模型中得到的标称项。通过添加补偿建模误差、干扰等的第二项来纠正这个动作。为了计算修正量,考虑模型在标称状态周围的线性化,并进行优化以计算控制动作。仿真结果验证了该方法的有效性。

Model-based controller for anesthesia automation
This paper presents an approach to anesthesia control using a model-based controller. General anesthesia with propofol is considered. The proposal tries to take advantage of the benefits of model-based controllers to improve the performance of control in anesthesia. The controller proposed is based on the application of two control actions. First, a nominal term is applied obtained from the inverse dynamics model. This action is corrected by adding a second term that compensates modeling errors, disturbances, etc. To compute the correction, a linearization of the model is considered around the nominal state and optimization is performed to compute the control action. Several results obtained in simulation are presented to test the efficiency of the method.
