Abstract

In this article we propose a modification to the first order Linearly Implicit Quantized State System Method (LIQSS1), an algorithm for continuous system simulation that replaces the classic time discretization by the quantization of the state variables. LIQSS was designed to efficiently simulate stiff systems but it only works when the system has a particular structure. The proposed modification overcomes this limitation allowing the algorithm to efficiently simulate stiff systems with more general structures. Besides describing the new method and its software implementation, the article analyzes the algorithm performance in the simulation of a complex power electronic converter.

一种改进的线性隐式量化状态系统方法
本文提出了对一阶线性隐式量化状态系统方法(LIQSS1)的改进,这是一种用于连续系统仿真的算法,它通过状态变量的量化取代了经典的时间离散化。LIQSS的设计是为了有效地模拟刚性系统,但它只在系统具有特定结构时才有效。提出的改进克服了这一限制,使算法能够有效地模拟具有更一般结构的刚性系统。本文在介绍新方法及其软件实现的基础上,分析了该算法在复杂电力电子变换器仿真中的性能。
