Designing an adequate control mechanism for this highly non-linear system needs precise modelling. This paper presents our new, accurate and simple approximation model of PAM, comparing with measured and literary data

Th e design of a stable robust position controller for PAM is difficult since it is a very nonlinear timevariant controlled plant because of the compressibility of air, air mass flow rate through the valve, etc. The main contribution o f this paper is a robust position control method based on sliding mod e for a robot arm, driven by pneumati c muscle actuator. Finally, it presents experimental results

The early control methods were based on classical linear controllers and then some modern control strategies have been developed (e. g. adaptive controller, sliding-mode controller, fuzzy controller, neural network controller and others) ([1], [2] and [3]). This paper presents a humanoid upper arm and discusses its positioning using sliding-mode control.

For people affected by stroke, frequent physical therapy has been suggested to be a successful rehabilitation. The use of robotic devices to assist the therapies is becoming more commonly, but traditional robots are usually stiff. The devices have to be able to provide the treatment way of repetitive practice. More and more devices consist of pneumatic artificial muscles (PAMs) as a good solution for actuators. There is a need for affordable, economical, low cost, lightweight, practical, low stiffness, multi-dimensional and low noise operation devices to assist therapy. In this paper we present some possibilities of use of PAM in rehabilitation devices.

The most made and common type of these artificial muscles in use is the McKibben artificial muscle that was developed in 1950's. The braided muscle is composed of gas-tight elastic bladder, surrounded by braided sleeves. Typical materials used for the membrane constructions are latex and silicone rubber, while nylon is normally used in the fibres. This paper presents the geometric model of PAM and different MATLAB models for pneumatic artificial muscles. The aim of our models is to relate the pressure and length of the pneumatic artificial muscles to the force it exerts along its entire exists.

Different designs have been developed, but the McKibben muscle is the most popular and is made commercially available by different companies (e. g. Fluidic Muscle manufactured by Festo Company). The most often mentioned characteristic of PAMs is the force as a function of pressure and contraction. In this paper our newest function approximation for the force generated by Fluidic Muscles is shown that can be generally used for different muscles made by Festo Company.

The controller is implemented on a TMS320LF2407 DSP based controller board. The advantage of the proposed algorithm for position control is the accuracy better than 10 µ m, approved through the wide range of dynamic and static load (disturbance) variation in the entire operation area. The paper describes the nonlinear model of the pneumatic cylinder and the three main design steps of the proposed control method ; sliding surface design, control law selection and chattering free implementation. The large number of experimental tests on the servopneumatic system with proposed sliding mode algorithm confirmed high accuracy and robustness in the horizontal and vertical position control.
