重型矿用电动轮车调速过程节能控制理论与方法研究

传统的重型矿用电动轮车节能策略为机电系统优化与制动能量回馈，皆因受动力机械本体与电气/器成本制约而难以奏效。尽管目前主流的传动系统“恒功调节”优化控制方法还在继续发展，但“被动”功率匹配策略与惯用控制指标缺陷等因素导致节能效果欠佳。本项目研究重型矿用电动轮车启动加速与运载调速过程节能控制理论，提出了调速过程“主动”功率匹配的能耗自寻优智能控制方法。该方法在建立两类过程能耗模型基础上，提出融入运载过程能耗的控制系统综合性能指标，并以此构建调速过程优化评价（目标）函数，设计出兼顾动、静态性能与能耗指标的运载过程能耗自寻优智能控制算法，以实现运载调速过程驱动功率的“主动”匹配。项目研究成功有望建立重型矿用电动轮车运载调速过程控制的能耗优化理论体系，为此类高能耗装备提供全新的节能技术手段，显著提高其节能效果，并为其他大功率驱动且频繁作业的高能耗系统提供可借鉴的节能控制方法。

Mine electric wheel truck (Mine Truck) is a kind of heavy carrying equipment with high energy-consumption. The strategies for its efficient energy-consumption are traditionally by means of mechanical & electrical system optimization and braking energy recovery. But the effect is often offset by the power mechanic itself or the cost for the electricity engineering or electric appliances. The mainstream optimization control has been the constant power adjustment to the drive system with continuous improvement, but this “passive” power-matching strategy with defective control index has not realized its ideal energy-efficiency. The project aims to research on the Mine Truck Energy-efficiency Control of Starting-Off Acceleration and Speed Regulation, and proposes a Self-optimization control for active power-matching in speed regulation. By establishing an Energy Consumption Model for the two kinds of process, we propose a comprehensive performance index for the energy consumption in operation, resulting an optimized evaluation (task) function for speed regulation, and finally work out a design for an intelligent energy-optimized control algorithm considering dynamic and static performance and energy efficiency indexes for Mine Truck Operation, realizing the active match for the power of speed regulation in operation.The success of this project is promising in establishing a theoretical system for energy-consumption optimization of the speed-regulation process control for Mine Trucks. It will provide brand-new technologies of easy energy saving and cost reduction for all such high energy-consuming devices, with substantial energy efficiency improvement. It can also provide inspiring methods for the energy efficiency control for all other highly powered drives and high energy-consuming systems of high working frequencies.
