Development of Energy Efficient Optimal Control for Servo Pneumatic Cylinders

چکیده
Abstract The paper conducts energy efficiency analysis of servo pneumatic actuator systems and presents a method of energy efficient optimal control. The system is linearised through input/output state feedback and then energy efficient optimal control theory is applied to the linearised system. An optimal control strategy is developed with respect to the transformed states of the linear system model. An energy efficient velocity profile is derived which depends on the final state and initial state. Through the inverse transformation, the new states are converted back to the original system state and control variable. In this way, a nonlinear energy efficient controller is derived for the servo pneumatic actuator system.

Parallel robots exhibit high stiffness, low weight and low dynamic forces, mostly because of the closed loop chains implied by their structure, and allow the positioning of the actuators on the truss. These characteristics outline the possibility of actuating such kind of robotic devices by means of pneumatic actuators. The position control of pneumatic cylinders through proportional valves sat...
متن کاملSelf-tuning control of a low-friction pneumatic actuator under the influence of gravity
Traditionally the positioning of pneumatic actuators has been limited to movement between preset stops or switches. The restricting factors preventing the use of pneumatic cylinders for accurate servo-control arise from highly nonlinear dynamic properties such as air compressibility and friction effects, which combine to severely degrade time response and positional accuracy. Many real systems ...
