Research Activity

  • Issues and aim:
    The framework of my research is to develop and control assisting devices to help elderly people and fragile in mobility patients. The issue is how the control can be suggested to create a comfortable behaviour for the user.

  • Results :

  • New Protocols – New Criteria. 

    • Energy and Trajectory : A study of sit-to-stand motion performed with a impedance control and a position control. The impedance evolution is used to determine the best trajectory to follow

    • Ecologic Test : A sit to stand and walking protocol has been invented and tested with old people in hospitals, this protocol is able to show the state of mobility ability of the patient while using a smart-walker device.

  • Model Human Disease

    • Linear Cerebellar Disease : Delay hypothesis in feedback term show a quite good representation of the human cerebellar response. It allows to show that a predictive controller is a good way to help stabilize this kind of patient.

    • Linear Parameter Variable : Knee Model during the walk with changing parameters based on knee angular value. 

    • Non-Linear : Synergy model of Sit-To-Stand Motion based on neural network, called "Partially Autofeed Neural Predictive Observer", this learning method and neural network description were able to show good ability to predict human diseased motion. Even if it is using robotic device.

  • ”Patient Able” Control

    • Fuzzy-Based Intention detection : This detector shows its intuitiveness while used by 10 diseased patients with a very small failing ratio.

    • Adaptative Parameter Selection : This method is a gaussian process model of parameters exploring method to reduce uncertainty with a very small number of iterations.
