For the uncertainties of the vehicle steering system, a method of equal control is used. The equal control input is calculated based on the certain part of the steering system, and a RBF network is used to apply the switch control input by compensating the uncertainties. The simulated results show that the twitter using the method presented in the paper is smaller than the strategy using fixed control...
The system states error using classical sliding mode control cannot converge to zero in finite time, so in this paper, a dynamic Terminal sling mode control method based on back stepping design is presented. Terminal sliding mode control strategy is employed to make tracking error converge to zero in finite time. A novel sliding differential dynamic surface is designed to attenuate the chatting. Furthermore,...
Firstly, with the blackboard rulers the steering system and wheels get their coordinated control tasks based on their own states and the vehicle's state. It can adjust desired commands and control paraments of the servo controllers to realize the vehicle's steering antilock brake stability. The force distribution strategy suitable for complex conditions is designed. Secondly, it realizes the servo...
A synchronization method of adaptive backstepping sliding-mode control is presented based on the multiscroll chaotic systems with hysteresis nonlinear function and unknown parameters. The strategy is designed by a step-by-step procedure interlacing. At each step, a coordinate transformation, the design of a virtual control via a Lyapunov technique and the definition of a tuning function are derived,...
In this paper, an active queue management (AQM) controller is designed for the problem of congestion control. In TCP networks, the packet-dropping probability function is considered as a control input. Thus, a TCP/AQM controller is modeled as a time-varying delay system with a saturated input. The objective of the work described here is to design robust controller capable of achieving the desired...
A new method is presented for designing robust tracking controllers for time-delay systems with parameter uncertainties. Assuming that the system satisfies the matched conditions, it is controlled to track dynamic inputs generated from a reference model. The resultant controller can guarantee uniform ultimate boundedness of tracking errors and the bounds can be made arbitrarily small
An approach to the design of robust tracking controllers is proposed for a class of large-scale interconnected linear uncertain systems with time-delays. The systems may contain time-delays in both states and controls. With the decentralized controller, the closed-loop system will asymptotically track the reference output. Numerical simulations have demonstrated the effectiveness of the approach proposed.
