  • Minimum-time trajectory control of a two-link flexible

    This paper analyzes the experimental results of model-based and sensor-based control strategies for a two-link flexible, planar, robot arm. An off-line optimization determines a minimum time, straight line tip trajectory which stays within the torque constraints of the motors and ends in a quiescent state, i.e. no vibrational transients.

  • First-Order Dynamic Modeling and Control of Soft Robots

    Typically, this has to be performed using some optimization techniques irrespective of the modeling strategy. A good example is the use of trajectory optimization for the control of a soft robotic manipulator using a model-based (Marchese et al., 2016) and model-free method (Thuruthel et al., 2017). This process is time consuming and hence
