A so-called lumped disturbance is considered in the T-S fuzzy model of the system to be controlled. Under the circumstances, this paper proposes two controllers, in which one is designed only on the basis of the control system stability, and the other is designed on the basis of both the control system stability and a proposed disturbance observer. Simulation results make a comparison between the...
This paper presents a controller integrity monitoring method for a class of second-order nonlinear uncertain systems incorporating neural network-based adaptive control algorithms. The adaptive neural network model is employed to ensure robust tracking performance in the presence of certain modeling uncertainty under consideration during the offline controller design process. Based on Lyapunov stability...
In order to improve the control performance, a so-called lumped disturbanceis considered in the polynomial fuzzy model. As a result, two fuzzy controllers are proposed, in which one involves a disturbance observer. Though both controllers are able to stabilize the control system, computer simulations conclude that the performance by the one with the disturbance is better than the other when it comes...
By the development of biosensor, signal processing techniques and critical technical breakthrough, the concept of brain-computer interface has been extended and emphasized that the interface between brain and electromechanical equipment is involved rather than just computer. This development leads to the formation of new technical theoretical system — brain control technology. In this paper, the development...
In this paper, according to the old people's physical characteristics and their technical requirements for comfort and mastery when operating the robot, a detection and recognition method of tactile and slip senses is proposed that used to control the Elderly-assistant & Walking-assistant Robot. First, on the basis of the proposed drive control system program of tactile and slip, detection system...
In metallurgy, chemical industry and medicine production, etc plants, batching precision determines final quality of their production. To ensure the high quality of the production and enhance competitive power of these companies, it is very important that a high precise batching control system to fit for an automation producing lines was studied. In this paper, a networked and intellectual precise...
Based on the working conditions and development trend of operating mechanism of high-voltage circuit breaker, this paper presented a high-load adjustment rate of portable high-frequency switching power supply designed for high-voltage circuit breakers test. The main circuit topological structure is analysed in detail, which uses the fullbridge circuit and IGBTs (insulated gate bipolar transistor)...
