摘　　要：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。In this paper, a multivariable self- tuning feedforward decoupling PID controller is presented, which is suitable to control non-minimum phase system and can realize the static compensation for measurable disturbance. Utilizing Jury methods the condition that stabilizes closed - loop system with an arbitrary delay is determined. The experimental result of an electric wind tunnel of an injector driven transonic wind tunnel demonstrates the effectiveness of the controller.
