Optimized torque‐distribution control method (OTCM) is a critical technology for front/rear axle electric wheel loader (FREWL) to improve the operation performance and energy efficiency. In paper, longitudinal dynamics model of FREWL created. Based on model, objective functions are that weighted sum variance mean tire workload minimal total motor efficiency maximal. Four nonlinear constraint optimization algorithms, quasi‐newton Lagrangian multiplier method, sequential quadratic programming,...
A classical control problem for an isolated oversaturated intersection is revisited with a focus on the optimal policy to minimize total delay. The difference and connection between existing continuous-time planning models recently proposed discrete-time are studied. gradient descent algorithm convert plan of model in many cases. Analytic proof numerical tests also presented. findings shed light links two kinds models.
In order to analyze the response of a hydraulic turbine variation in operating conditions, different laws time mass flow rate have been considered. After validating overall numerical framework through comparison with relevant experiments, performances considered analyzed from fluid-dynamic point view. The results show that profiles (in this work, for simplicity, referred as “transition functions”) varying influence on transient behavior turbine. When quadratic function is case large flow,...
