Application of backstepping single neuron PID compound control to servo system

In view of wide variations of inertia moment and loads and large disturbed moment in a rocket launcher position servo system, backstepping single neuron proportion-intergration-differentiation(PID)compound control is presented. The online parameter adjustments of the proportion, integral and differential of the conventional PID controller are realized by the single neuron PID, achieving the adaptive control of the system. The backstepping algorithm can guarantee the big system error converges to set value quickly and improves the adaptive ability. Simulation and experimental results show that the compound control strategy has better stabilization and dynamical tracking accuracy.
