Automation Technology

Pneumatics has greatly progressed as convenient multifunctional automation technology. One typical application is in compact light-weight highperformance pneumatic actuators. The introduction of control theory has also enabled useful pneumatic servosystems. New actuators include pneumatic artificial rubber muscles, which are small, light-weight, and soft. These are used for applications in the medical, welfare, and nursing fields. This special issue focuses on actuator development in drive-circuit analysis and design. Issues in these areas include pneumatic actuators, pneumatic rubber muscles, pneumatic circuit analysis and design, energy-saving, pneumatic servocontrol, advanced control systems, industrial applications, automation, vehicles, entertainment, medical, welfare and nursing applications, and education. This special 13-article issue is divided into (i) control design and pneumatic cylinder and bellows applications and (ii) the development and applications of soft pneumatic actuators. Some types of soft pneumatic actuators use artificial rubber muscles for welfare and rehabilitation equipment. This special issue should prove useful in understanding state-of-the-art of pneumatic technology applicable to analysis, design, control, and application in innovative machine design. I would like to express my sincere appreciation to all of the authors and reviewers for their invaluable effort.

Low Efficiency

Pneumatic actuators, due to their unique features, have numerous industrial applications. However, when compared to electrical actuators, one of the major problems of the overall pneumatic system is low-efficiency. Thus it is important to develop control algorithms for force tracking of pneumatic actuators while minimizing the consumed energy. This paper presents three different approaches for force tracking of pneumatic cylinders. A dual-action pneumatic cylinder along with a real-time control platform were used to compare the energy efficiency and force tracking performance of these methods. Experiments with sinusoidal forces reveled that minimizing the chamber pressure gives the best tracking performance and energy efficiency in higher frequencies.

One Step

The study of reconfiguration problems has grown into a field of its own. The basic idea is to consider the scenario of moving from one given (feasible) solution to another, maintaining feasibility for all intermediate solutions. The solution space is often represented by a “reconfiguration graph”, where vertices represent solutions to the problem in hand and an edge between two vertices means that one can be obtained from the other in one step. A typical application background would be for a reorganization or repair work that has to be done without interruption to the service that is provided.
