چکیده
The aim of this research is to compensate the multivariable system’s Tele-control performance and preserve the stability of closed-loop system. Generally, in Tele-control systems, it contains two time-delay elements that have influence on design of the input signals and processing of output signals. Therefore, the closed-loop performance of the system is unstable and tracking characteristic of the output becomes worse due to time-delay elements. Moreover, in multivariable system, the interferences cause harmful influence against the desired output signals. In this research, we propose the new effective compensator for the plant that has time-delay elements and interferences. The designed compensator is consists of low frequency and decoupling controller. Therefore, closed-loop system is stabilized and reduced the interference. Furthermore, the effectiveness of the proposed compensator is verified by carrying out the control of pitch angle and angular velocity of wind-turbine simulator system.

Time-delay identification is one of the most important parameters in designing controllers. In the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. In this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (MIMO) system has been presented. This method is ba...
متن کاملOptimal characteristics determination of engine mounting system using TRA mode decoupling with emphasis on frequency responses
It is possible to improve vehicle vibration by tuning the parameters of engine mounting system. By optimization of mount characteristics or finding the optimal position of mounts, vibration of the engine and transmitted force from the engine to the chassis can be reduced. This paper examines the optimization of 6-degree-of-freedom engine mounting system based on torque roll axis (TRA) mode deco...
