Linear vapor compressors are becoming more widely utilized in refrigeration applications due to their high efficiency as compared with traditional rotary devices. The nature of the free piston in a linear compressor allows the system resonant frequency to vary with the force of gas compression. In order to ensure efficient operation of the compressor the motor must be excited in such a way as to ensure...
The contribution addresses the problem of robust trajectory tracking control and disturbance rejection for a non contact, high-precision Lorentz force planar motion stage of linear DC brushless type. The control problem is accomplished by using a composite control law including a simple computed torque type controller together with an extended Luenberger type of state and disturbance observer also...
A global sliding mode control scheme is proposed to force an underactuated surface vessel to track a desired trajectory, in spite of the presence of uncertain parameters and unmodelled uncertainties including external disturbances and measurement noise, etc. The effect that the rudder generates a lateral acceleration on the sway direction is considered. In this case, the system is nonminimum phase...
Exoskeleton suit is a typical human-machine system. Control the exoskeleton suit to track the pilot's moving trajectory as well as to minimize the human-machine interaction force. The suit will help decrease the pilot's power consumption and assist the pilot to carry heavy load. Impedance control was introduced to the control of exoskeleton suit. As the control laws that based on the dynamic model...
