By analyzing the various factors affecting the current carrying capacity of power cable in actual operating environment, the mathematical model of temperature change of cable in the actual operation can be obtained. On this basis, establishing a dynamic relationship between its real-time current carrying capacity and operating temperature, and solving by algebraic equations and differential equation...
An approach for distribution network planning considering distributed generators(DGs) is proposed in this paper. It determines the optimal placement and capacity of distributed generators in power distribution network without considering the feeder changes and substation upgrades. The corresponding planning model is built and the particle swarm optimization with inertia weight (PSO-w) is used to solve...
The control problem under the condition of uncertainty is an important subject of modern control field. In most control problems, the actual control object and mathematical model for the controller design are always present differences. These differences come from the object parameter uncertainty and time-varying, etc. Mill hydraulic position servo system is the complex nonlinear control system with...
This paper shows that a comprehensive multivariable approach of autopilot design that mixes sliding mode and PID leads to robustly satisfactory results for underwater mobile robot. The 6-DOF linear equations of motion can be divided into three subsystems for speed control, steering, and diving. The sliding mode algorithm is designed for steering control and PID is used for diving and speed control...
How to get rid of the cumulative errors of the cross seal system is one of the key problems for packaging quality. Through the theoretical deduction, the movement regularity of double-crank slide composite horizontal seal mechanism has been ascertained. According to the periodic property of the horizontal seal, the repetitive control strategy has been proposed to increase the system steady-state accuracy...
Hydraulic bending roll system has become one of key equipments to control the exit strip shape in strip rolling mills. The hydraulic bending roll system of a hot rolling mill was researched and analyzed, and its mathematics models were founded in whole based on the action principle of some representative hydraulic components. At last, the hydraulic bending roll system was simulated with MATLAB by...
Abstract-Because the request to the quality of cold rolling sheet strips is higher and higher, the hydraulic AGC (Automatic Gauge Control) has been a requisite means for improving the quality of cold rolling strips' finished products. But the PID control strategy, being comprehensively used in the locale, is difficult to satisfy the request of improving the control precision of cold rolling mill,...
