In order to solve the problem that the controlled system depends on the mathematical model in the cement particle size control, and further to improve the robustness and stability of the controled system, a data-driven online adaptive PID control method is proposed. Firstly, the cement mill process is briefly introduced, and a relevance is reached that the speed of the posterior separator is the key...
A robust adaptive terminal controller is proposed for attitude system of near space vehicle. Firstly, NSV dynamic model is presented, which includes nonlinear, uncertainty and disturbance. Secondly, an second order sliding mode disturbance observer is used to estimate the unknown disturbance. Then, in order to overcome the chattering problem in traditional sliding mode, the design process of second-order...
In order to use the method based on model to study the accurate control of cement combined grinding system, and improve its automatic control level, this paper proposes a extreme learning machine (ELM) online modeling method for combined cement grinding system. First of all, this paper analyzes the process of combined grinding system, based on the analysis of the process, we know that the speed of...
In order to solve the problem of the traditional intelligent mower, which cannot cover the lawn area and operate complexly, a visual, wireless, autonomous mower system via machine vision is designed. Firstly, collect the image information of locale dynamically by the real-time camera which erected on the high bracket, and display on the monitor of PC, then draw a few mowing range or mowing patterns...
