Design of a Digital Controller for Fiber Optic Gyroscope Based on PID Algorithm with Partial Differential
The discrete transfer function of system is deduced according to the operational principle of digital closed loop Fiber Optic Gyroscope(FOG). In order to eliminate steady-state error and improve the dynamic performance FOG, a method of designing the digital controller in detection circuit based on PID algorithm with partial differential is proposed. By combining with the neural network and the optimal control theory, a single-neuron learning algorithm based on quadratic performance index is applied implement the adaptive adjustment of the controller’s parameters, and a recursive algorithm is given. The simulation results indicate that with such a digital controller steady-state error of the system is zero, the adjusting time shortened by 60%, the systematic overshoot can be eliminated, the high frequency noise can be suppressed effectively, and system shows strong stability and robusticity. Both the static and the dynamic performance of FOG can be obviously improved.
