Design and Implementation of Discrete Time Observer Based Backstepping Controller for a 2DOF Servomechanism
The two degrees of freedom servomechanism has many applications, including in gimbaled seekers. These mechanisms require closed-loop control to perform properly. In this paper, an observer-based multi-input-multi-output hybrid controller is designed for a two-degree-of-freedom servomechanism. Since in the model presented in this paper, disturbances on the mechanism are considered, so an extende...
متن کاملLMI results for robust control design of observer-based controllers, the discrete-time case with polytopic uncertainties
Design of robust observers is considered in the context of linear discrete-time, time invariant systems. Robustness is achieved with respect to polytopic type uncertainties that affect the dynamics of the plant. At the difference with the uncertainty-free situation, state-feedback / observer separation principle does not hold. Therefore, the observer design has to take into account the state-fe...
متن کاملA Robust Control Design Technique for Discrete-Time Systems
A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...
متن کاملA Robust Adaptive Observer-Based Time Varying Fault Estimation
This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...
متن کاملHyperplane Design in Observer-based Discrete-time Sliding Mode Control Hyperplane Design in Observer-based Discrete-time Sliding Mode Control
A new result that allows the selection of sliding hyperplane coeecients in Observer-Based Discrete-Time Sliding Mode Control (OBDSMC) is presented. Selection of co-eecients is done by analyzing the tracking error dynamics inside the boundary layer-where the closed-loop system has a linear state feedback connguration-rather than assuming that the sliding function has already converged to zero. T...
