aThis example shows how to design feedback and feedforward compensators to regulate the temperature of a chemical reactor through a heat exchanger. 这个例子怎么显示对设计反馈和feedforward补偿器通过热转换器调控一个化学反应器的温度。[translate]
The process includes equipment to recycle unreacted monomers and solvent. The recycle stream introduces disturbances to the reactor feed, which perturb the polymer properties. A feedforward control strategy is proposed to counter these disturbances, and its effectiveness is demonstrated using the model. ...
The developed algorithms provide a way to calculate the time-varying minimum-variance feedforward and feedback control benchmark from routine operating data. The proposed techniques are illustrated through a simulated stirred-tank heater example and an industrial application.关键词: Feedforward and Feed...
As discussed in class, feedforward and feedback controllers are both useful. In real-world systems, they are often used together; a simple example is shown here: Consider the problem of balancing an inverted pendulum on a cart(see the Project Descript...

A scheduling architecture for real-time control tasks is proposed. The scheduler uses feedback from execution-time measurements and feedforward from workload changes to adjust the sampling periods of the control tasks so that the combined performance of the controllers is optimized. The performance of...
The present experimental work demonstrates the use of feedback and feedforward control methods to attenuate rotor vibrations. The experiments were performed on a rotor test rig having a 3-kg rotor supported by journal bearings. The critical speed of the rotor was about 50 Hz. The objective was...
First, we linearize the nonlinear dynamics of the piezoactuator by accounting for the hysteresis (as well as creep) using high-gain feedback control. Next, we model the linear vibrational dynamics and then invert the model to find a feedforward input to account vibration - this process is ...
