Get Price(A car's cruise control is a PID controller.) The PID algorithm is surprisingly simple, and can be implemented in five lines of code. There are three constants that must be determined in order to shape the control's output. The three constants as well as the set point and sampling interval can be changed in real time.

Get PriceOrigins. Continuous control, before PID controllers were fully understood and implemented, has one of its origins in the centrifugal governor, which uses rotating weights to control a process.This had been invented by Christiaan Huygens in the 17th century to regulate the gap between millstones in windmills depending on the speed of rotation, and thereby compensate for the variable speed of

Get PriceCone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materials. Control systems for cone crusher setting (CSS) are widely used to compensate for wear and to protect the crusher. With a frequency converter the eccentric speed in a cone crusher can be adjusted in real-time. The eccentric speed of the main shaft affects the number of compressions the
Get PriceDefinition. A piecewise linear function is a function defined on a (possibly unbounded) interval of real numbers, such that there is a collection of intervals on each of which the function is an affine function.If the domain of the function is compact, there needs to be a finite collection of such intervals; if the domain is not compact, it may either be required to be finite or to be locally
Get PriceCone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. In this thesis real-time optimization is explored to the

Get PriceSemidefinite programming (SDP) is a subfield of convex optimization concerned with the optimization of a linear objective function (a user-specified function that the user wants to minimize or maximize) over the intersection of the cone of positive semidefinite matrices with an affine space, i.e., a spectrahedron.. Semidefinite programming is a relatively new field of optimization which is of

Get PriceIn a following work, the authors implemented a real-time optimization of a cone crusher without a control system for CSS by instead controlling the eccentric speed dynamically ( Hulthén and Evertsson, 2008 ). This improved the output from the crushing stage by 4.2%. It also increased liner lifetime dramatically with 27%.
