Artificial Neurological Control of Artificial Skin for Aeronautical Applications
J. Jim Zhu, Ohio University
The recently developed electroactive polymeric smart materials can be used for many novel sensor and actuator applications. In particular, the possibility of fabricate large pieces of electroactive polymers with massively distributed collocated actuator and sensor pairs, which could be called artificial skins, may enable novel aeronautical applications such as conformal flow separation control for improving lift-to-drag ratio, or flapping wing micro aircraft. To facilitate such applications, a key technology is dynamic modeling and control of the massively distributed actuator-sensor pairs. In this talk we propose a neurological control paradigm that mimics the biological nervous system. The control architecture is hierarchical where local sensory and motor neurons react to the environment to achieve local optimality and learns by evolutionary alteration of connectivity, and higher level control consists of fast dynamical motion controls and complex logical event control. This control architecture could be applied to the piezoelectric and electrostrictive polymeric blend material for conformal flow separation control. Material dynamical modeling and control system implementation issues will be identified for discussion.
