Robust Control for Bidirectional Stabilization System With Time Delay Estimation

Nonlinear Robust Control of Vehicle Stabilization System with Uncertainty Based on Neural Network

“…In this paper, τ = σ(x u )s T is taken to guarantee the bounded stability of the final controller. Bringing Equation (24) into Equation ( 17…”

“…In addition, the adaptive rate can compensate the error term in the control process and improve the stability of the system around the ideal tracking angle. To further deal with the uncertainties in tank vehicle stabilization systems, extended state observers [22,23] and time-delay estimation techniques [24] have also been applied to the precise pointing motion of tank guns. In [22,23], the design of the disturbance observer is used to estimate and compensate the mechanical dynamic uncertainty of the vehicle stabilization system, which is an effective way to reduce the influence of friction nonlinearity and structural flexibility of the mechanical system to a certain extent.…”

“…In [22,23], the design of the disturbance observer is used to estimate and compensate the mechanical dynamic uncertainty of the vehicle stabilization system, which is an effective way to reduce the influence of friction nonlinearity and structural flexibility of the mechanical system to a certain extent. According to [24], the complex modeling of the mechanical dynamics of the system is avoided by the time-delay estimation technique, the system's lumped uncertainty is estimated, and the finite-time stabilization of the tank vehicle stabilization system is obtained by incorporating sliding mode control. The above control methods promote further improvement in control performance of vehicle stabilization systems and are effective treatments for uncertainty in vehicle stabilization systems.…”
