– This paper aims to present a robust design approach to realize disturbance attenuation for a yaw – pitch gimballed system subject to actuator saturation and disturbances.
– To minimize the impacts of disturbances in the presence of saturation nonlinearity and acquire desired response performance, the control approach is of double closed-loop configuration. State feedback controllers are synthesized via convex optimization and used to stabilize the inner loops; robust controllers are synthesized via mixed H ∞ optimization and used to stabilize the outer loops.
– It is shown through performance simulations that the proposed control scheme is effective in terms of command following, stability and disturbance attenuation.
– The presented robust control approach provides a theoretical method to facilitate designing a stable servo control loop for a yaw – pitch gimballed seeker.
– This paper supplies an effective way of addressing stabilization problem induced from actuator saturation and system uncertainties.
