This paper is concerned with the control strategy implementation for antenna servo systems. A linear active disturbance rejection controller (LADRC), which can estimate and compensate unmodeled dynamics and bounded disturbances in real time, is proposed. The field programmable gate array (FPGA) is utilized to design a control integrated circuit (IC). The procedure of achieving control objectives by...
This paper proposes a modeling, design and verification platform with a fast sizing and biasing methodology. We introduce a simple and efficient method to implement an interface between non-conservative system-level models and their circuit-level realizations. Simulation tools such as SystemC AMS and Spice simulators are combined with a sizing and biasing tool. Moreover, a transient simulation method...
Wire electrical explosion (WEE) in vacuum was studied through a 0D model coupled with circuit configuration following the model proposed by Beilis and co-workers. The results were compared with their simulation results. With this model, the influences of some factors including current rise rate and plasma density were analyzed.
This paper presents a unified platform for design and verification of mixed-signal systems based on the SystemC AMS standard. The platform relies on a top-down design methodology. In this methodology, several hierarchical abstraction views of the system are considered. These abstraction levels are: system, functional, macromodel and circuit levels. We introduce a simple and efficient method to implement...
Three dimensional network-on-chip (3D NoC) is motivated to achieve better performance, functionality, and packaging density compared to 2D NoC. To facilitate performance evaluation for the design stage, an accurate and flexible environment for simulating the 3D NoC performance is necessary. In this paper, we present a complete high-level simulation platform for 3D NoC called Meshim, based on SystemC,...
Introduces the application of Proteus in microcomputer principle teaching, including the solutions of bus timing and NMI interrupt. The circuits and codes are given. Practices prove that the Proteus simulation can make breakthrough in these difficulties.
Two-dimensional electromagnetic (EM) particle-in-cell simulations were performed to study the effect of the displacement current and the self-magnetic field on the space-charge limited current density or the Child-Langmuir law of a short-pulse electron flow with a propagation distance of ζ and an emitting width of W from the classical regime to the relativistic regime. Numerical scaling of the two-dimensional...
