System modeling and computer aided simulation have been increasingly used in vehicle engineering to reduce development time, improve and simplify complex systems. A Type C Electronic Power Steering (EPS) modeling and simulation program has been developed based on Matlab. The aim of this simulation is to simulate completed system dynamic behavior regarding optimizing main parameters of system model.
Most of existing active queue management (AQM) algorithms were designed on the fluid model of TCP/AQM dynamics which ignores the slow start and TCP timeout mechanism. Modeling TCP flows more precisely is very important to study AQM performance. To address this problem, this paper develops the step response model of TCP/AQM network based on the dumbbell topology in NS2. Then a novel AQM algorithm (DM-AQM)...
With the development of the high speed and high precision machines, the linear feed drive system has been developing very fast during the last two decades. Compared with the traditional ball screw feed drive, the linear motor feed drive system eliminates all mid- transmission mechanism and exhibits the properties of high velocity, high acceleration, long stroke, fast dynamic response and etc. However,...
For the speed control of film winding system, the pseudo-derivative feedback (PDF) controller is first selected. Controller parameters tuning then becomes a nonlinear constrained optimization problem with nonlinearity and load variations of film winding system. To avoid the selection of penalty parameters in constraint handling, NSGA-II is utilized by converting the nonlinear constrained optimization...
To solve the non-linear system control problem in the hydraulic servo control system, the self-adapting fuzzy-PID control of variable universe is introduced. By analyzing the phase plane characteristics of step response, the fuzzy control rule base which decreased cases of relying on experts' experience was established. According to error variety, the discourse universe of the input and output fuzzy...
This paper analyzes the step load response of a current-mode-controlled pulsewidth modulation (PWM) converter and also presents design guidelines for obtaining a good step load response. Analytical expressions for the step load response are derived in terms of the power stage and feedback compensation parameters. Control design to minimize the overshoot and settling time of the output voltage is presented...
