MPC-ESO POSITION CONTROL STRATEGY FOR A MINIATURE DOUBLE-CYLINDER ACTUATOR CONSIDERING HOSE EFFECTS

Miniature hydraulic actuators are especially suitable for narrow-space and harsh environment arrangement.However, when using thin and long hoses to connect components, the volume expansion caused by pressurized oil inside can have significant adverse effects on the performance of the miniature system.Moreover, the volumetric variation relates to ma

Aim.To assess the size of the alveolar ridge / part of the jaws in patients with gnathic mesial occlusion of the dentition.Materials and methods.A study was carried out, during which we determined the structural features of the alveolar ridge of the upper and lower jaws of 50 adult patients (from 18 to 44 years old), and also studied the presence /
