Learning Time Optimal Control of Smart Actuators with Unknown Friction
Active valves are most effective tools to control gas flow in compressors if fast transitions between the open mode and closed mode are needed. Unfortunately, an accurate model including several nonlinear effects and in particular the resistance and gas flow forces is not available, and this prevents the use of standard model based approaches for time optimal control. However, the repetitive na...
متن کاملActive vibration control using compliant-based actuators
In this work, an active vibration control method using compliant-based actuators is proposed for controlling a wide range of vibration and its noise-associated applications. The compliant-based actuator combines a conventional actuator with elastic elements, such as passive springs, that can be demonstrated to have better accuracy and robustness for force control compared to conventional stiff ...
متن کاملActive Control of Nonlinear Dynamic Response of Space-frames Using Piezo-electric Actuators
A scheme for active control of nonlinear vibration of space-structures, wherein each member is modeled as a beam-column, is presented. The expressions for shear stresses transmitted to the structural member by the distributed segmented piezo-electric actuators, which are bonded on the surfaces of the member, are derived in the general case in which the structural member is subjected to moments,...
متن کاملOptimal Placement of Actuators and Sensors for Vibration Active Control
Optimal placement of actuators and sensors is an important issue in vibration active control. An index for joint consideration of controllability and observability based on singular values of Hankel matrix is described at first, then an objective function according to the index is defined for actuator and sensor placement. A genetic algorithm procedure (GA) is adopted to solve the optimization ...
متن کاملACTIVE NOISE AND VIBRATION CONTROL LITERATURE SURVEY: Sensors and Actuators
This study arose from the need to control noise in naval vessels to reduce their detectability and hence vulnerability to enemy attack. In this report a detailed review of sensor and actuator technologies that could be used for active noise and vibration control in ship structures has been provided. The review focused on a wide range of sensor and actuator materials, such as piezoelectric and e...
