  Author(s): Myong Song Ryu*
  
  With the development of industrial automation technology, pneumatic position servo control systems are widely used using fast switching solenoid valves instead of expensive proportional valves or servo valves. However, the fast switching solenoid valve has a bad effect on the position control characteristics due to its inherent nonlinear nature. Therefore, it is necessary to use a suitable control method to compensate for the nonlinear behavior of the fast switching solenoid valve and to construct its accurate nonlinear mathematical model. We constructed firstly an air, machine, electrical and electronic model of a fast switching solenoid valve using AMESim and, on this basis, propose a new nonlinear model of a fast switching solenoid valve controlling pneumatic servo position control system. In addition, a Fuzzy-PID switching control system was.. View More»
