The research status of robotic excavator was introduced and the electro-hydraulic system schematic diagram of test excavator was analyzed. On the base of principle of load independent flow distribution system, the mathematical model of test excavator was derived. The reference model for adaptive control was given after logically simplifying electro-hydraulic model by combination of theory and experiment...
In this paper, we consider the problem of designing traffic network signal control systems for congested urban road networks, aiming to relieve traffic congestion and improve the utilization of the existing traffic infrastructures. A Model Predictive Control (MPC) method is introduced which is based on a microscopic store-and-forward modeling (SFM) paradigm. Moreover, a preliminary simulation of urban...
In this paper, the nonlinear H∞ guidance law design is proposed for the near space interceptor (NSI) based on Galerkin simultaneous policy update algorithm (GSPUA). Initially, the nonlinear H∞ guidance law design problem for the NSI is converted to solve the Hamilton-Jacobi-Isaacs (HJI) equation, which is notoriously difficult to solve both numerically and analytically. In the two-player zero-sum...
The accelerated thermal aging test with controlled air was performed at 170°C for 216 hours, using the oil-paper insulation samples which were composed of BIOTEMP oil, NOMEX paper and pressboard. Some aging indicators including degree of polymerization of pressboard, dielectric strength of oil, acid value of oil, furfural concentration of oil, and water content, etc, were measured and recorded during...
This paper addressed the scheduling problem in a press job shop environment. A heuristic-based scheduling model is proposed by analyzing the characteristics of bi-directional press line. The objective is to improve the machine utilization rates and to balance the load of production lines, with the consideration of machine constraints, operation constraints and batch constraints. A novel heuristic...
