Feedforward control is an open-loop scheme that compensates the system dynamics without needing information about the system states as the tracking error. From: Modeling and Nonlinear Robust Control of Delta-Lik
A feed forward power control loop is provided for a tissue stimulation system. The tissue stimulating system includes an external device and an implantable device. Only the amount of power required by the implantable device is transmitted across a transcutaneous transmission link to the implantable ...

We begin with an overview of feedforward control and ratio control, a special type of feedforward control, is introduced next. 对于反馈控制本身不能令人满意的情况,可以通过增加前馈控制来实现控制的重大改进。但要使用前馈控制,必须在线测量(或估计)干扰因素。在本单元中,我们考虑前馈控制系统的设计和分析...

Key words :velocity loop controller, pseudo derivative feedback with feedforward gain controller, feedforward controller, parameters tuning, IMP 1 一、前言 近年來,PC 工業技術快速地發展已經深深影響到機械製造業,而目前國內雖有中、 小型廠商設計研發 CNC 運動控制器,但受限於國內市場狹小與資金不足...
The technique provides feedforward compensation which introduces an additional zero of the closed-loop system transfer function. Using a PD-feedback compensator in addition to the feedforward one “almost” pole-zero cancellation of the dominant closed-loop poles of the system is achieved. The ...
TheACIM Feed Forward Controlblock decouplesd-axis andq-axis current controls and generates the corresponding feed-forward voltage gains for field-oriented control of the induction motor. The block accepts feedback values ofd-axis andq-axis currents and the mechanical speed of the rotor. ...
