Grinding circuit control: A hierarchical approach using ...

A hierarchical method using extended 2-DOF decoupling and model approximation is proposed to control the grinding circuit. The resulted hierarchical system consists of a lower-level control system (LLCS) and a higher-level setting system (HLSS). The PID-based LLCS is responsible for forcing the key process variables to track the given set ...

Decoupling capacitor - Wikipedia

A decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect it has on the rest of the circuit. An alternative name is bypass capacitor as it is used to bypass the power supply or other high impedance component of a circuit.

Grinding circuit (GC) of mineral processing industry is characterized by its multivariable, high interacting, time-varying parameters and large measurement delay nature. The product particle size and the circulating load of the GC are two important production indexes that directly related to performances of the subsequent beneficiation process and production rates of the overall mineral ...

Capacitors - learn.sparkfun.com

Decoupling (Bypass) Capacitors. A lot of the capacitors you see in circuits, especially those featuring an integrated circuit, are decoupling. A decoupling capacitors stone is to supress high-frequency noise in power supply signals. They take tiny voltage ripples, which could otherwise be harmful to delicate ICs, out of the voltage supply.

Decoupling (electronics) - Wikipedia

In electronics, decoupling is the prevention of undesired coupling between subsystems.. A common example is connecting localized decoupling capacitors close to the power leads of integrated circuits to suppress coupling via the power supply connections. These act as a small localized energy reservoir that supply the circuit with current during transient, high current demand periods, preventing ...

The invention relates to an ore grinding process operation control method based on a multivariable decoupling (IMC) technology, belonging to the technical field of automatic control. The method comprises a bottom layer loop control system which communicates with an upper computer through a network, and an upper layer loop setting system that is embedded into the upper computer, comprises a ...

Multivariable decoupling internal model control for ...

Grinding circuit (GC) of mineral processing industry is characterized by its multivariable, severe coupling and multiple time delay nature. The product particle size and the mill throughput of GC are the important performance indexes directly related to the performance of the subsequent process and the production rate of the overall mineral processing plant respectively.

IC power pin connection for noise immunity and decoupling ...

With circuit A you get less spike at the IC Vcc pin and more ring, and with circuit B, the opposite is true. Note the current in the trace to the capacitor in circuit B though, it reverses. The other option you have not shown is to put the power plane via under the IC so the trace lengths are equal.
