In this study a real-time open loop estimate of the disturbance displacement input to the tire and an external disturbance force, representing handling and aerodynamic forces, acting on the sprung mass of a quarter-car suspension test rig was generated. This information is intended for use in active control methods applied to vehicle suspensions. This estimate is achieved with two acceleration ...

Multi-axis hydraulic rigs are widely used in industrial testing applications but still represent a challenging area for control system design. The current paper considers the control of a six-degrees-of-freedom multi-axis shaking table driven by six hydraulic actuators. The strategy adopted employs adaptive decentralized position control, i.e. each axis has its own adaptive controller. The sche...

Refrigeration is a process of maintaining the temperature lower than surroundings. It can be achieved with help components refrigerator and refrigerant. Refrigerant substance atmosphere. VCR widely applied in daily as well large scale industry to produce refrigeration effect. The diffuser passage that will increase pressure energy by changing kinetic at inlets. main objective this project work ...
