Linear programming problems with alternate solutions are challenging due to the choice of multiple strategiesresulting in the same optimal value of the objective function. However, searching for these solutions is atedious task, especially when using mixed integer linear programming (MILP), as previously applied tometabolic models. Therefore, judgment on plurality of optimal m...

this paper presents a new hybrid method for optimal multi-objective reconfiguration in a distribution feeder in addition to determining the optimal size and location of multiple-distributed generation (dg). the purposes of this research are mitigation of losses, improving the voltage profile and equalizing the feeder load balancing in distribution systems. to reduce the search space, the improv...

in conventional direct torque control (dtc), the stator flux is usually kept constant by controlling the x-axis component of the stator voltage in the stator flux reference frame. the torque is then controlled by the y-axis component of stator voltage. in this scenario, the stator current does not exceed its permissible value. however, in the so-called optimal efficiency mode, the induction mot...

In this paper the optimal control of boundary heat flux in a 2-D solid body with an arbitrary shape is performed in order to achieve the desired temperature distribution at a given time interval. The boundary of the body is subdivided into a number of components. On each component a time-dependent heat flux is applied which is independent of the others. Since the thermophysical properties are t...

a bearingless induction machine has combined characteristics of induction motor and magnetic bearings. therefore, the advantages are small size and low-cost. in the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. the suspension forces are generated taking an advantage ...
