For LEMS short-term prediction intervals (a few minutes to hours) are effective over medium- and long-term prediction (effective for planning and risk management). The predicted powers (PV: P PV, WPGS: P S ) are treated as references to the control hierarchy (i.e. consists of primary, secondary and independent DG controllers [ 2 ]).

The grinding process has particular interest in that contact temperatures have great significance for quality and integrity of machined surfaces. Hardened surfaces may be damaged by softening and or being stressed, being hardened or re-hardened, burned or cracked. It is important in grinding for the fluid to remove heat from the grinding contact zone to avoid thermal damage to the workpiece ...
