数值模拟结果表明,作为控制工程中最常用的反馈方案之一,比例积分控制可以将可激介质中的传播波段稳定到所需的尺寸。比例积分控制器测量波段的大小,并向介质施加空间均匀的信号。该控制器具有以下特点:不需要进行艰难的试错调整,无需重新调整控制器即可将波段稳定到不同的大小,即使在具有位置相关参数的介质中也可以保持波段大小。
Numerical simulations are performed to demonstrate that proportional-integral control, one of the most commonly used feedback schemes in control engineering, can stabilize propagating wave segments in excitable media to a desired size. The proportional-integral controller measures the size of a wave segment and applies a spatially uniform signal to the medium. This controller has the following features: difficult trial-and-error adjustment is not necessary, wave segments can be stabilized to different sizes without readjusting the controller, and the wave segment size can be maintained even in media having position-dependent parameters.
