چکیده
This paper tackles the disturbances in control operation in close-loop and its effect on the system by studding transfer function in presence and absence of disturbances. An example controlling a mechanical system is taken and the unexpected outside element effect consider here as disturbance, the close-loop feedback transfer function of the system. The model of the mechanical system is showing the effect of the disturbances obviously to the all system.

متن کاملControl of Flexible Link Robot using a Closed Loop Input-Shaping Approach
This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...
متن کاملEffect of Disturbance Directions on Closed-Loop Performance
The effectiveness of disturbance suppression in a multivariable control system can depend strongly on the direction of the disturbance. The “disturbance condition number” is introduced to quantify the effect of disturbance direction on closed-loop performance. As an example a two-point composition control system for a distillation column is analyzed for various disturbance and set-point changes.

This paper presents a robust ∞_H controller design, based on a generalized dynamic observer for uncertain singular systems in the presence of disturbance. The controller guarantees that the closed loop system be admissible. The main advantage of this method is that the uncertainty can be found in the system, the input and the output matrices. Also the generalized dynamic observer is used to est...

This paper focuses on the effects of closed- control on the calculation of the dynamic load carrying capacity (DLCC) for mobile-base flexible-link manipulators. In previously proposed methods in the literature of DLCC calculation in flexible robots, an open-loop control scheme is assumed, whereas in reality, robot control is achieved via closed loop approaches which could render the calculated ...
