“…With the given assumptions and simplifications, the state-space representation describing the actuator's behavior can be written in a single form as (30)- (32), but the values of these matrices depend on the actual states indirectly through (19), (20), (21) and (33), which results in two versions of A and four versions of B matrices; therefore, it has eight hybrid states, where the actual state is determined by the mass flow rates and the Main piston position.…”

“…In [33], a nonlinear model is proposed, fitted to a given actuator, and used effectively for controller design. However, the model developed for this research had to be able to predict the effects of constructional changes, thus a more universal model was needed, based on conservation equations, such as the conversation of energy and conservation of momentum.…”

The paper presents the modeling and control design of a floating piston electro-pneumatic gearbox actuator and, moreover, the industrial validation of the controller system. As part of a heavy-duty vehicle, it needs to meet strict and contradictory requirements and units applying the system with different supply pressures in order to operate under various environmental conditions. Because of the high control frequency domain of the real system, post-modern control methods with high computational demands could not be used as they do not meet real-time requirements on automotive level. During the modeling phase, the essential simplifications are shown with the awareness of the trade-off between calculation speed and numerical accuracy to generate a multi-state piecewise-linear system. Two LTI control methods are introduced, i.e., a PD and an Linear-Quadratic Regulators (LQR) solution, in which the continuous control signals are transformed into discrete voltage solenoid commands for the valves. The validation of both the model and the control system are performed on a real physical implementation. The results show that both modeling and control design are suitable for the control tasks using floating piston cylinders and, moreover, these methods can be extended to electro-pneumatic cylinders with different layouts.

“…A PAM motion caused by a nonlinear force that mainly depends on parameters like pressure and deformation is obtained analytically by applying the optimal parameter identification method. This method has finally been proved and tested on an experimental rig by Sárosi et al [61] and Palomares et al [62]. Cullinan et al [63] and Cveticanin et al [64] have investigated the steady state position of the mass of the system and the force influenced by the pressure of the PAM mathematically and experimentally.…”

A Review on the Development of Pneumatic Artificial Muscle Actuators: Force Model and Application

2022

Pneumatic artificial muscles (PAMs) are soft and flexible linear pneumatic actuators which produce human muscle like actuation. Due to these properties, the muscle actuators have an adaptable compliance for various robotic platforms as well as medical applications. While a variety of possible actuation schemes are present, there is still a need for the development of a soft actuator that is very light-weight, compact, and flexible with high power-to-weight ratio. To achieve this, the development of the PAM actuators has become an interesting topic for many researchers. In this review, the development of the different kinds of PAM available to date are presented along with manufacturing process and the operating principle. The various force models for artificial muscle presented in the literature are broadly reviewed with the constraints. Furthermore, the applications of PAM are included and classified based on the fields of biorobotics, medicine, and industry, along with advanced medical instrumentation. Finally, the needful improvements in terms of the dynamics of the muscle are discussed for the precise control of the PAMs as per the requirements for the applications. This review will be helpful for researchers working in the field of robotics and for designers to develop new type of artificial muscle depending on the applications.

“…There are many approaches to the analysis and modelling of pneumatic suspensions. In some cases these analyses are based on experimental observations, such as in [5], where is proposed an analytical model of air spring suspension which includes only the air spring, the auxiliary reservoir and the connecting pipe, in [6], where is developed a model of a controlled pneumatic spring or in [7], where two mathematical modelling approaches, a quasi-static one and a dynamic one, are developed. In [8] are reviewed existing models for railway vehicle suspension components and their use for railway vehicle dynamics multi-body simulations, a particular importance being given to the pneumatic suspensions.…”

The pneumatic elastic elements are widely used in the secondary suspension of modern railway vehicles due to their important advantages compared to the conventional ones. In the present paper, the modelling and analysis of the pneumatic suspension is approached, taking into account the main elements, pneumatic enclosures and rubber elements. The analysis performed investigates the influence of relevant parameters on suspension stiffness and on its dynamic response.
