Abstract


With the rapid development of aerospace technology for inertial navigation equipment performance requirements are also rising. The turntable as its main test and simulation equipment , and accordingly its performance requirements are also constantly improving . In this paper, the classical control theory and pole placement self-tuning PID control theory were carried out turntable control system design, while using the S -curve algorithm as the turntable traction input. Since the classical control theory simple structure, designed to facilitate , in the actual control there is still a wide range of applications . In this paper, the classical theory of classical PID control method designed turntable position loop and speed loop. Which, in order to facilitate debugging , using only the velocity loop proportional component , the position loop is proportional , integral and derivative control method , and in the position loop introduces a filter. This system simulation analysis shows that this method is still effective turntable control system control method . In the actual control system, due to various effects , the controlled object is often uncertain. To overcome the uncertainty of the object model to study the self-tuning PID control pole configuration . The method of least squares line identification controlled object , and changed in real time controller parameters . Simulation results show that this method has good tracking performance and robustness . Turntable operation requires good stability, large step will cause the system to control the amount of output saturation . This paper studied traction turntable input, using S-shaped curve algorithm traction input method as a turntable , thus avoiding the major problem step . This traction input method in actual control of the turntable to get a good control effect.
