In order to ensure the consistency of the closed-loop system performances, before the AFC is applied, a supervisory controller is used to drive initial tracking errors to a preset closed area, and then the AFC can drive the tracking errors of the closed-loop system to pre-specified neighborhood in the presence of unknown approximation errors of the fuzzy logic system.

为保证系统性能的一致性，在启动自适应模糊控制器前，采用监督控制将初始跟踪误差镇定到给定范围。自适应模糊控制器可在存在模糊逻辑系统逼近误差的情况下，使系统跟踪误差小于预先给定的任意常数。

It is proved that the"feedback linearization" certainty equivalence control law with"regressor vector-based"update law can guarantee the real output to track reference output in relative degree one case.

当控制对象的相对阶为1时，我们证明了采用"反馈线性化型"确定性等价控制律，和"基于回归向量"的自适应律，可以保证实际输出有界跟踪参考输出；当控制对象的相对阶大于1时，控制律和自适应律的结构保持不变，但是构造自适应律的信号采用了由跟踪误差得来的"增广误差"。

A new switching scheme to the gain of variable structure control signals is proposed. The following important open problems in standard VS-MRAC and MRAC are solved by using the scheme: 1 . a prespecified transient and steady-state performance index for tracking error can be achieved without requiring any information about the plant high frequency gain sign when relative degree of modelled part of plant is one, and 2 . it is shown that as long as the performance indexes are guaranteed for the auxiliary errors, each of which in dynamics is a sub-system with relative degree one, the tracing error will converge to a small residual set in a prespecified transient time when relative degree of modelled part of plant is greater than one.

提出了一种控制增益可切换的变结构自适应律，解决了如下变结构模型参考自适应控制（包括基于调参律的模型参考自适应控制）理论研究中长期没有解决的问题：当对象建模部分相对阶为1、高频增益符号未知且存在非线性输入扰动和未建模动态等情况下，系统跟踪误差可满足预先给定的动态和稳态性能指标；当对象建模部分相对阶大于1且存在非线性输入扰动和未建模动态时，可保证系统跟踪误差在预先给定的过渡过程时间内收敛到一个残差集中； 5。

本文针对MS跟踪和粒子滤波跟踪各自的优缺点，将其两者进行了很好地结合，提出了两步跟踪算法，其特点有：保留了MS跟踪实时性的优点的同时，也具有粒子滤波在遮挡情况下的鲁棒性等特点；在所需的每步粒子跟踪中，以上一步的跟踪结果与模板的相似度为先验知识，自适应地选取粒子个数和传播半径，缓解了粒子缺乏多样性的缺点，也根据这个相似度来判断是否需要对目标模板的更新，保证了更新的有效性。

To settle the problem, this article brings about a hybrid algorithm by combining the mean shift and the particle filter tracking technique on the basis of the color histogram distribution. By adopting the strategy that the number of particles is adaptively determined, it amalgamates the virtues of the two techniques. It reduces the computational cost and ensures the performance simultaneously.
