GDI汽车发动机怠速时滞依赖的H∞控制（Delay-dependent H∞ Control of GDI Engine under Idling Mode）
GDI发动机 怠速控制 时滞依赖 状态反馈
2010/12/29
基于时滞影响的GDI发动机非线性平均值怠速系统模型，针对怠速工况下汽车附件用电产生的扭矩干扰量，设计了时滞依赖的H∞状态反馈控制器，使闭环控制系统渐进稳定同时，满足输出量对扰动输入的抑制能力为γ。该时滞既包括发动机稳态下的燃油喷射到力矩输出时间延迟，瞬态下节气阀控制进气量这一时刻到这部分进气量实际进入缸内的时间延迟，还包括节气阀执行控制量动作的延迟。上述时滞参数都是不确定的并且时不变的，但分别有...
Delay-dependent stability analysis for discrete singular systems with time-varying delays
Discrete singular systems time-varying delays delay-dependent stability linear matrix inequality (LMI)
2010/3/29
This paper studies the problem of stability analysis for
discrete singular time delay systems. Without resorting to the
decomposition and equivalent transformation of the considered
system, some ne...
Delay-Dependent Stability for Systems with Fast-Varying Neutral-Type Delay via A PTVD Compensation
Linear neutral systems stability delay-dependent fast-varying neutral-type delay
2009/9/9
The stability for a class of linear neutral systems with time-varying delays is studied in this paper, where delay in neutral-type term includes a fast-varying case (i.e., the derivative of delay is m...
Delay-Dependent Stability Criteria for Singular Time-Delay Systems
Delay-dependent stability singular systems linear matrix inequalities (LMIs)
2009/9/9
This note studies the problem of singular time-delay systems. At first, the equivalence among several recent stability criteria is established, and a simplified version is derived. By using a delay de...
A New Delay-dependent Absolute Stability Criterion for Lurie Systems with Time-varying delay
Lurie system time-varying delay absolute stability nonlinearity linear matrix inequality (LMI)
2010/3/29
The problem of absolute stability analysis for Lurie systems with time-varying delay and
norm-bounded parameter uncertainties is considered. By using a new Lyapunov-krasovskii functional
which split...
