Disturbance Rejection Control in Coordinated Systems
نویسندگان
چکیده
Abstract: Coordinated system control with realistic disturbance is studied. We employ coordinated vehicles as an working problem. Vehicles attempt to keep a specified formation while avoiding collision in the presence of disturbance such as a wind gust. State estimators are used to estimate the self-states and the states of interacting vehicles via communication channels. Estimation performance is incorporated into control design and plays a central role in control performance. A numerical design approach is used to overcome limited knowledge about the disturbance and noises. A case study is given to demonstrate central ideas of the paper.

متن کاملVoltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control
Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent. This controller is used in a double loop structure including an inner current loop and oute...

This study investigates disturbance rejection capacity of closed loop control systems by means of reference to disturbance ratio (RDR). The RDR analysis calculates the ratio of reference signal energy to disturbance signal energy at the system output and provides a quantitative evaluation of disturbance rejection performance of control systems on the bases of communication channel limitations. ...

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...
