【Abstract】 In this paper, the dynamic specifications for a control system are put intothe constraints of the system outputs, and minimizing the maximum constraint violation becomes our goal. So we can solve the proboem of the nonlinear control design by using aconstrained optimization. With this ibea, we have optimized the digital PID controller of aload sensing pump by using sequential quadratic programming method. The simulation hasproved that this method is feasible and efficient.更多还原
