  • Servo control of the composite controller based on combined given curve

    • 摘要：

      The requirements of the plate straightening process on the response process of hydraulic cylinder in the praxis were studied, a concept of combined given curve was proposed to alleviate the impact of the system with large mass and inertia during the response for the step and ramp signals and its harm on the whole system. Combined with the nonlinear PID control backed up by the tracking differentiator, a composite controller was proposed based on the combined given curves of the displacement, velocity and acceleration. The feasibility and practicality of the proposed algorithm were verified by simulations and the practical application in the full-hydraulic straightening machine.
