This complex, during its almost 100 years of operation, has undergone significant modifications and enhancements mainly due to technological changes driven by the replacement of steam traction by electric traction, and then by diesel-electric traction. Despite this, the complex maintained an impressive architectural consistency. Unfortunately, most of the buildings of this complex are unused and in disrepair, being the target of invasions, vandalism and theft of materials that if not stopped will cause irreparable damage to its structure and to the local ambience. The question that appears most urgent, therefore, is to seek ways to repossess this group of workshops in order to meet the current demands of urban development without losing the characteristics which form its architectural and urban identity in a city in accelerated mutation.展开更多

To tackle this problem, an optimal control strategy called rule-based equivalent fuel consumption minimization strategy （RECMS） is developed for a new complex hybrid electric vehicle （CHEV）. It optimizes the energy efficiency and drive performance to cater for normal and power-loss operations of the tractive motor. Firstly, the strategy formulates a novel objective function based on the equivalent fuel concept. By accounting for the actual fuel cost, the equivalent fuel cost for the electric machines and virtual fuel cost for the drivability, the cost function is obtained. Furthermore, some penalty factors are presented to optimize the performance target. Finally, experiments for a practical CHEV are performed to validate a simulation model. Then simulations are carried out for both rule-based and RECMS. The results show that the optimal energy management is working well.展开更多
