Low-cost, non-polluting pneumatic technology is one of the most important engineering
technologies. However, the application of pneumatic servo system is limited by the low …

In this Note, a nonlinear dynamic model of a PWM-driven pneumatic fast switching valve is
presented. The electro-magnetic, mechanical and fluid subsystems of the valve are …

A pneumatic actuator with solenoid valves is a discontinuous-input system because each
valve can be either in on or off state. For such an actuator, this paper proposes a sliding …

In this study, a non‐singular fast terminal sliding mode finite‐time tracking control strategy is
presented to improve response rapidity and control precision of a pneumatic servo system …

Pressure servo control plays a crucial role in the majority of industrial applications that use
compressed air as their power source. How to reduce the energy consumption of the …

The design, modeling and position control of a novel hybrid pneumatic–electric actuator for
applications in robotics and automation is presented. The design incorporates a pneumatic …

Clutch-to-clutch shifts are ubiquitous in automatic transmissions, motivating the need for
formal and robust methods for controlling these shifts. Limited sensing in production …

For robotic systems that use on/off (solenoid) pneumatic actuators, a sliding mode control
law for precise position control and low switching (open–close) activity of the valves is …

Actuators used in robot arms need to be powerful, precise, and safe. We present the design,
implementation, and control of a novel rotary hybrid pneumatic-electric actuator (HPEA) for …

In this paper, the effect of pneumatic circuit design on the input–output behavior of PWM-
driven servo-pneumatic systems is investigated and their control performances are improved …
