A New Methodology to Design Sliding-PID Controllers: Application to Missile Flight Control System
نویسنده
چکیده
In this paper, a new methodology to design robust sliding-PID tracking motion controllers for a certain class of nonlinear systems is presented. The methodology is based upon the combination of the conventional PID control, sliding-mode control in Filippov’s sense, and relative degree concepts. The tracking of desired motion trajectories is performed in the presence of nonlinearities, modeling uncertainties, and external disturbances. The proposed methodology is successfully applied to the pitchaxis autopilot design for a tactical missile. High-level performances, robustness, and fast convergence of the closed-loop system are guaranteed.

Traditionally, missile autopilots have been designed using linear control approaches with gain scheduling. Autopilot design is typically carried out in the frequency domain and the plant is linearized around various operating points on the trajectory. Moreover, three single axis autopilots are usually designed without considering the interaction among the motion axes, i.e., the autopilots in ea...
