This paper proposes a fuzzy state feedback controller of depth control for unmanned underwater vehicle (UUV) to solve the communication time-delay problem resulting from application of the Network Control System (NCS). Firstly, we adopt T-S fuzzy reasoning method to express the vertical plane dynamics time-delay model of UUV. Secondly, by using Parallel Distributed Compensation(PDC) strategy, a state...
Learning and memory, which are important functions of the human brain, are the foundations of thinking. Revealing the learning and memory mechanism of human brain is the core objective and main development way of the intelligent science. Improved human brain functional structure model, a memory prediction structural framework on the brain structure and function are proposed. And then we work out a...
In the past, the research on PWM pneumatic linearized system mainly focused on control method and electro-magnet switch features, there are little reports on the structural parameter design of pneumatic valve and the mathematical model of pneumatic part. This article took the PWM servo system of the double-acting cylinder as example, discussed the linear analysis method of PWM pneumatic system, given...
In the paper, model of looper height control system with the disturbance, input-delay and constraints on control input are analyzed. In view of engineering practice, a class of robust model predictive control algorithm based on the LMI is presented, where constraints on control input are taken into account to prevent large input stretching the strip and doing harm to hot strip mills. Further more...
