The goal of this paper is to present a new robust hybrid method that ensures stiffness of the mechanical characteristic of the direct current motor servo drive, which means lack of influence of the varying load torque on quality of the velocity control, what extends the concept of the MFC-V (model-following velocity control) system that allows one to shape the servo drive transient response, ensuring,...
In this paper, the method of adaptive control with fractional order reference model was proposed. By introducing the fractional order calculus theory into control fields, it became much easier to promote the performance than integer order control system. Combining fractional order control theory and the traditional model reference adaptive theory, a new controller design was provided which added a...
A new scheme of using generic model control based on input equivalent disturbance (AGMC) to design controller is presented for nonlinear electro-hydraulic servo control systems. It is very easy to tune for the controller whose parameters are of very explicit physic meaning. The influence on control performance of time-varying parameters and unmeasurable disturbances can be effectively compensated...
At present, controller design of industrial processes with long time-delay is still a difficult problem. Furthermore, the time-varying and nonlinear features, which enhance the difficulties, are often encountered in the processes. According to analyzing the characteristic of a human-simulated intelligent controller (HSIC), the schema of the HSIC is proposed to deal with the processes of long time-delay,...
