At the same time, both the FB and FF controls are combined together with utilization of the dynamic characteristic compensation. As a result, the stable and highly accurate control is attained with a feedback/feedforward controller.広井 和男...
The feedforwardcontrol schemein Figure 3.1.3 can provide better control of the liquid level. Here the steam flow rate is measured and the feedforward controller adjusts the feedwater flow rate so as to balance the steam demand. Note that the controlled variable, liquid level, is not measured...
PURPOSE:To improve the control accuracy and to ensure the stable control by performing only the feedback FB control with the feedforward FF control system stopped in accordance with the level of a static characteristic compensation component signal or combining both the FB an FF controls with utili...
A control system has two main goals: get the system to track a setpoint, and reject disturbances. Feedback control is pretty powerful for this, but this video shows how feedforward control can supplement feedback to make achieving those goals easier.
To further improve control performance feedback compensation using traditional PID scheme is adopted to integrate with the feedforward controller. 展开 关键词: Prandtl-Ishlinskii model the Bouc-Wen hysteresis model Particle swarm optimization DOI: 10.1109/ICAMechS.2014.6911563 被引量: 5 ...
It consists of PI and feedforward controller adapted online. A stability analysis of the adaptive control configuration is provided. Simulations using a cloud service model taken from the literature illustrate the performance of the system under various conditions. The use of adaptation significantly ...
Minimum variance feedback control is the best possible feedback control in the sense that no other controllers can give lower process variance. If a process indicates a good performance measure relative to minimum variance control, further tuning of the existing feedback controller is neither useful...
