High-Accuracy Force Control With Nonlinear Feedforward Compensation for a Hydraulic Drive Unit

The hydraulic drive unit (HDU) applied in a hydraulic drive legged robot joints adopts an outer loop impedance control method based on the hydraulic control's inner loop during motion so that the entire system obtains certain compliance characteristics. There are two types of inner loops, namel...
