Multi-Objective Optimization in Cement Grinding Process: A Time Domain Rolling Optimization Method Based on CIE-MOCS Algorithm
2023 42nd Chinese Control Conference (CCC)(2023)
Abstract
Power consumption and cement specific surface area (SSA) are two essential production indexes in the cement grinding process. It is of great significance to reduce power consumption while ensuring the qualified SSA for the cement grinding process. However, power consumption and SSA are a pair of conflicting objectives with multiple dynamic interferences, resulting in unqualified product quality and excessive power consumption. This paper proposes a multi-objective optimization method for the cement grinding process to solve this problem. This method takes power consumption and SSA as the optimization objectives to establish a multi-objective model. In addition, to solve the problem that static single-step optimization cannot match the actual working conditions, this paper proposes a time-domain rolling CIE-MOCS algorithm (TRCIE-MOCS) to optimize the model. This algorithm consists of a population updating strategy, a selection strategy, and a time-domain rolling strategy. Through experiments, it is proved that TRCIE-MOCS can reduce power consumption while ensuring cement quality.
