this paper deals with optimal operation of a three-product dividing-wall column (dwc). the main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. exact local method is used to find the best controlled variables as single measurement or combination of measurements base...

An approach for the optimal control of both velocity and torque split of a parallel hybrid electric vehicle with traffic preview is presented in this paper. The optimal controller is analytically derived using Pontryagin’s Minimum Principle. The optimal velocity and torque split trajectories developed are then repeatedly recalculated in a receding horizon fashion over drive cycles to assess the...

in this paper, a non-isothermal two-phase flow in the cathode gas diffusion layer (gdl) of pem fuel cell is modeled. the governing equations including energy, mass and momentum conservation equations are solved by numerical methods. also, the optimal values of the effective parameters such as the electrodes porosity, gas diffusion layer (gdl) thickness and inlet relative humidity are calculated...

Batteries in a fuel-cell power system are essential to providing the additional power during the sharp load-transients. This necessitates a power-electronics subsystem (PES), which controls the energy flow between the fuel-cell stack, the battery, and the application load during the transient and in the steady states. In this paper, a distributed PES (comprising a multimodule dc-dc boost conver...

This paper presents a reinforcement learning (RL)–based energy management strategy for a hybrid electric tracked vehicle. A control-oriented model of the powertrain and vehicle dynamics is first established. According to the sample information of the experimental driving schedule, statistical characteristics at various velocities are determined by extracting the transition probability matrix of...

There are several kinds of metrics should be handled by the brake system of hybrid electric vehicles such as fuel economy, performance and safety. The optimal control of the HEV brake system will be solved by a modelbased approach. Based on the developed vehicle model, a two phase approach is proposed for the coordinated control of the HEV brake system. A high level sliding mode controller is a...
