Adaptive Boundary Control of a Flexible Three-Dimensional Euler–Bernoulli Beam with Input Signal Quantization

With the development of control theory, network control has become a hot spot and the control method has gradually changed from traditional analog control to digital control. By combining control and communication, it is possible to solve the control problem of signal transmission using information technology. However, in network control, the bandwidth of the digital channel is limited. In order to prevent problems such as data loss caused by congestion during signal transmission, the quantization process is often performed before transmission through the communication channel. The quantified system should be able to maintain the stability and meet the acceptable control accuracy when the bandwidth is as small as possible.
