提出一种多变量自校正前馈解耦PID控制器。利用Jury法确定了对任意时延、使闭环系统稳定的条件。该控制器适于非最小相位系统,可实现可测干扰的静态补偿。引射式跨音速风洞电子风洞的Mach数和稳定堤总压控制结果证明了该控制器的有效性。
A multivariable self-tuning feed-forward decoupling PID controller is proposed. Jury method was used to determine the conditions for any delay to stabilize the closed-loop system. The controller is suitable for non-minimum phase systems and enables static compensation of measurable disturbances. The numerical results of the Mach number and steady-state total pressure control of the wind tunnel induced by the transonic wind tunnel show the effectiveness of this controller.
