“…Unlike the classic HOSM, in the proposed controller, only the velocity is needed to be estimated by a differentiator from the position measurement. In the previous work [24], it has been shown that the differentiator has a strong influence on the performances of the controller. In the following experimental tests, the velocity is evaluated by the HOSM differentiator [11].…”

The objective of this brief is to propose a new third-order sliding-mode (TOSM) controller. The main feature of this controller is that it only requires the sliding variable and its first time derivative (whereas standard TOSM controllers are also using the second-order time derivative of the sliding variable). This reduction of the use of time derivatives is very important, because it reduces the noise introduced in the controller. Parameters tuning rules are also given. The control strategy is experimentally applied to an electropneumatic system. IndexTerms-Gain adaptation, high-order slidingmode (HOSM) control, pneumatic actuator.

“…In the case of pneumatic actuator position control, it means that the position, the velocity, and the acceleration should be estimated. In [24], several differentiators have been studied, in the context of pneumatic actuator control. Due to the measurement noise, it is difficult to guarantee the accuracy in the high-order differentiation.…”

a b s t r a c tIn this paper, a first strategy to reconstruct the piston position of a pneumatic cylinder supplied by two servovalves is proposed using only the chambers pressure measurements. This work focuses on the position observation at standstill. Starting from a classical model of this actuator, a transformation of the inputs is used. This way, for the first time, a link is established between electro-pneumatic actuators and Permanent Magnet Synchronous Motors (PMSM). This allows to apply PMSM zero speed observation strategies to electro-pneumatic actuators. Thus, following an observability analysis, a signal injection based methodology is used to ensure the observability of the electro-pneumatic system. A non-linear position observer is synthesized and a Lyapunov function is provided to ensure the global stability. Experimental results confirm the proposed strategy efficiency. The proposed technique constitutes a first step toward sensorless position control of electro-pneumatic actuators.

Pneumatic-hydraulic transmission has been developed for years. However, its dynamic properties are not good enough for application. In this paper, in order to increase the output characteristics, a late-model air-powered vehicle using expansion energy is proposed which can boost energy through a pneumatic-hydraulic transmission. The dynamic characteristics of the air-powered vehicle is modeled and verified by conducting experiment. In addition, the influence of the key parameters of the air-powered vehicle is researched for the optimization of the system performance. Through the results, the author got the conclusion that, firstly, comparison of the results of model and experiment proves the built model to be effective; secondly, input air pressure should be set according to the request of the practical loads, and range of 0.65 to 0.75 MPa can be chosen; thirdly, as a key structure parameter of the airpowered vehicle, ratio of the areas is considered to be set to approximate 8; what's more, a bigger orifice with a limit will promote the system dynamic characteristic property, and the limit is about 3.5 mm; last but not the least, not too farther position of the rings will increase the quality of output dynamic characteristics. This paper can be a reference for system design of air-powered vehicle and dynamic improvement.
