本研究针对多面体线性变参数系统，借由线性控制器组态重建控制器，以加密增益调度控制器。加密增益调度控制器计算控制输入，而不需要通过调度参数和设备状态计算的控制器增益和传输信号的原始数据。此外，在加密控制系统的控制器的量化器的设计问题被认为是保证渐近稳定，并提出了解决问题的方法。数值算例验证了加密增益调度的可行性，并证实了我们的量化器保证了稳定性，减少了由加密引起的量化误差。
This study considers encrypting a gain-scheduled controller for polytopic linear parameter varying systems by reconstructing the controller with the linear controller configuration. An encrypted gain-scheduled controller computes a control input without raw data of controller gains and transmitted signals, which are calculated by scheduling parameters and plant states. Additionally, a quantizer design problem in an encrypted control system with the controller is considered to guarantee the asymptotic stability, and a solution to the problem is proposed. A numerical example demonstrates the feasibility of the encrypted gain scheduling and confirms that our quantizers ensure the stability and reduces quantization errors caused by the encryption.
