This paper presents a model and controller design for a pneumatic actuator system. Three control strategies of position, force and compliance control are proposed. From the compliance control, stiffness characteristic of the pneumatic actuator will be presented in real-time system. Model of the pneumatic actuator system (transfer function) is obtained from System Identification (SI) method. Next, Predictive Functional control (PFC) with observer design is selected as the control strategy for the pneumatic system. Performance assessment of the controller is performed in MATLAB and validated through real-time experiment. Result shows that the PFC controller is adapted to the system and able to control successfully in both simulation and experiment.

Abstract This contribution presents a new approach of estimating the joint torques for an active orthosis. The new approach combines inverse dynamics and measured ground reaction forces. The joint torques can easily be computed from the ground reaction forces, but the measurement is usually flawed. An obsererver is employed to estimate the disturbance of the measurements and restore the original joint torques. A model of the human lower extremity is presented and additional seat forces are introduced to model the seat. Simulation results on the Sit-to-Stand movement illustrate the effectivity of the new approach.

Abstract For the implementation of modal control concepts for linear distributed-parameter systems knowledge of the modal coordinates is mandatory. Modal filters present an approach to extract these coordinates from a set of measurements. Using an array of sensors the design problem involves the choice of proper weighting coefficients and locations for the elements of the sensor array. In this contribution conditions on the sensor positions are derived using knowledge of the mode shapes to design modal filters that are exact for a maximal number of consecutive modes. The application of the given design process is illustrated by two examples.

Introduce Fressscale MC9S12XS256 as the core control unit of the self-tracing smart car system. Fast and accurate information extracting and processing is the guarantee of the sensitive smart car quickly moving along the track. To the smart car system based on electromagnetic technology, create one method of path position detection and its technology details. Tests show this method can be good at forward-looking,real-time and accuracy.
