  zero output
For the affine system with vector control, the problem of stabilization of the zero equilibrium position can be solved by stabilizing the zero output value, provided that the affine system is a minimum phase one.
      
In the case of non-constant returns, it is the cost structure in a neighborhood of the zero output that drives the market structure.
      
For TD, convergence can be enforced with a certain output condition assuring that the δ-error drops on average to zero (output control).
      
The relaxation were about 20% of the full contractions.3.Zy 16039 has no effect on the resting (zero) output of mucus in the ferret trachea.
      
Zero input voltage, for example, should produce a digital zero output.

  zero-output
This technique is proposed in order to decrease amplitude distortion of output signals that can be introduced by the robust DFT calculated within a wide interval including possible zero-output.
      
This implies that the closedloop system is O-GAS and zero-output dissipative, hence iISS.
      
We conclude that the system is 0-GAS and zero-output dissipative; hence iISS.
      
  null output
An important but less obvious point is the difference between the null output and deletion.
      
If correspondence is not a total bijective function in some candidate, then that candidate is an instance of the null output.
      
Still, the point remains that it is inflectional gaps that most clearly show the need for the null output as candidate.
      
Therefore, unlike the first option, it correctly distinguishes the null output from the candidate with maximal deletion.
      
We will examine the markedness properties of the null output below in section 4.2; for now, we will focus on its faithfulness properties.
      


The causes of disturbing electron current in quadrupole mass filter with Farady cylinder as an ion detector are described. Such current disturbs the zero out-put basic line of the light mass number region, so that it's very difficult to measure and record the height of spectrum peaks of the light mass number region. In order to eliminate such phenomena, we have suggested a kind of electoton-ion separator to replace Farady cylinder ion detector and have obtained better results.

An approach to stabilize a family of nonlinear systems via feedback nonlinearization is presented. A dummy output mapping is constructed so that the zero dynamics are made asymptotically stable and the system is of relative degree{1,…,1};then a group of controllers are designed that guarantee the exponential attractivity of the zeroing output manifold. Using tools in nonlinear H ∞ control  theory, it is shown that under mild conditions, the resulting closed loop system is locally asymptotically stable. Finally, these results are used to the attitude control problem for a rigid body to design detumbling controllers that only require knowledge of relative value of the system inertial parameters. This technique seems attractive in that, to a certain extent, it may lessen the need of precise system knowledge required by the feedback linearization technique.

给出了一类非线性系统的状态反馈非线性化镇定的方法。首先构造一个人为的输出映射,使得系统的零动态渐近稳定并具有向量相对阶{1,…,1};然后构造一类控制器使得零输出流形服从一类指数稳定的非线性动态方程。利用非线性H∞-控制一个基本结果证明了在较弱的条件下,所得到的闭环系统是局部渐近稳定的。最后以刚体姿态控制为例,说明了利用上述结果,可以得到一类仅仅需要知道系统惯性矩阵元素相对值的反馈方案,从而在一定程度上克服了反馈线性化方法需要精确知道系统参数的弱点。
