Abstract:

PID controller, input error adaptive controller and output error adapt ive controller have designed to study the vertical instability control of theHL-2A plasma. Simulation results show the three methods all satisfy the requirements of vertical position control system. The two adaptive control methods are more advantageous than the PID method on dynamic response properties and the robustness property for the adaptive controllers can continuously track dynamical changes within the system. The structure adopted output error adaptive control system is very simple and feasible.
