| titleOfInvention | Disturbance compensation control method for underwater electro-hydrostatic actuator |
| abstract | The invention discloses a disturbance compensation control method of an underwater electro-hydrostatic actuator. The method includes: a first expansion observer outputs an estimated value of an external load force to a state space model; a second expansion observer outputs a common estimated value of seawater pressure compensator disturbance and total leakage to the state space model; the backstepping controller outputs a second The virtual control quantity of step backstepping method; the virtual control quantity of the second step backstepping method is used as the speed of the motor of the underwater electro-hydrostatic actuator, so as to realize the precise tracking of the preset position of the underwater electro-hydrostatic actuator. . The method of the invention solves the problem of low control precision of the underwater electro-hydrostatic actuator, reduces the influence of disturbance through the feedforward compensation of the expansion observer, and improves the position control precision of the underwater electro-hydrostatic actuator. The backstepping controller ensures the stability and robustness of the overall system and provides a guarantee for underwater operations. |
