tailieunhanh - A grey predictor-based feedforward controller andIts application to force control of hydraulics system

This study presents a force control approach for an EHA system using a combination of a feedforward-based PID (FPID) controller and a grey predictor (GP), shortened as grey predictor-based feedforward PID Controller (GPFPID). The FPID controller is used to drive the system to desired targets. Meanwhile, the GP predictor takes part in estimating the output in the near future to optimize the controller parameters in advance and to create a compensating control signal corresponding to the system perturbations, consequently, improving the control performance. |
