Closed-loop force control for a semi-automatic

2021-1-12  A double closed-loop grinding force control system is designed to perform the grinding force control. This thesis develops the models of the servo system and the grinding process. Based on these models, a force controller is designed with the ability of tracking the desired force set point.

2009-7-1  Ball mill grinding circuits are essentially multi-variable systems characterized with couplings, time-varying parameters and time delays. The control schemes in previous literatures, including detuned multi-loop PID control, model predictive control (MPC), robust control, adaptive control, and so on, demonstrate limited abilities in control ball mill grinding process in the presence of strong

Dynamics and variance control of hot mill loopers

2008-1-1  Poor control of hot strip mill loopers degrades strip width and gauge, and may even lead to mill breakdowns due to instability. In this study, dynamics of the looper–strip system and the control challenges it poses are discussed, and covariance control theory is applied to variance control

3DOF Ball on Plate Using Closed Loop Stepper Motors

3DOF Ball on Plate Using Closed Loop Stepper Motors: The ball on plate problem consists of a flat plate on which a ball needs to be positioned. Ball positioning is only achieved through unstable equilibrium where any small changes in the plate angle will result in the continual acceleration of the bal

Observer design for state and clinker hardness estimation

2021-1-12  The cement mill, represented in figure 1, consists of a ball mill in closed-loop with a separator. The separator is driven by its rotational speed v (rpm). The rotating ball mill is fed with cement clinker at feeding rate u (tons/h), in which balls perform the breakage of the material particles by fracture and/or attrition. The output material

How does closed-loop stepper control work (and why

Stepper motor systems using closed-loop control represent a small percentage of stepper motor applications, but if loss of position could be catastrophic to the application, yet the system requires high torque at low speed, relatively simple architecture, and relatively low cost (compared to a true servo motor system) a closed-loop stepper might be the most appropriate solution.
