Particle Swarm Optimization for Optimal Powertrain parameters of parallel-series hybrid electric vehicles,"Presenter"

Detailed Information

Category(E)Hybrid EV Control I
Author(E)1) Tianjun Zhu
Abstract(E)This paper proposes a powertrain parameters design approach based on particle swarm optimization (PSO) algorithm. The optimization objective is to optimize transmission ratio and final drive ratio to achieve the minimization of fuel consumption with optimal vehicle performance. The original multi-objective optimization problem is converted into a single-objective problem with a goal-attainment method, and the principal parameters of powertrain are set as the optimized variables by PSO algorithm, with the vehicle performance indexes of parallel-series hybrid electric vehicles (PHEVs) being defined as the constraint conditions. The proposed strategy has been verified by the driving cycle under the MATLAB/Simulink software environment. Simulation results indicate that the proposed PSO-based powertrain parameters optimization method can achieve better fuel efficiency compared with traditional strategies.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
