This paper focuses on the position tracking control issue of electrohydraulic systems (EHS). The dynamical model EHS is introduced in first place, based which a type Variable Structure Disturbance Observer (VSDO) constructed for to estimate parametric uncertainty possesses. Then, backstepping controller designed under VSDO realize high precision purpose. To avoid phenomenon differential explosi...

This paper mainly expounds that using the WINSOCK controller which is provided by VB6.0 to program the procedures in the coop intelligent control system, it introduces the character of the TCP protocol and the UDP protocol, and according to the demands of the system environment to choose the suitable protocol. This system uses the WINSOCK controller and the UDP protocol for network communicatio...

The motor control system of unmanned aerial vehicle (UAV) will be affected by the environment during its operation, which has certain nonlinear characteristics. sliding mode variable structure method is proposed in this paper. Through pre design parameters and modes, influence interference, parameter changes, temperature other factors on reduced, power factor, precision working efficiency are i...
