A dynamic signal is introduced and adaptive nonlinear damping terms are used to restrain the effects of unmodeled dynamics, nonlinear uncertainties and unknown bounded disturbances.
      
Nonlinear optimal predictive controller for static var compensator to improve power system damping and to maintain voltage
      
The main objectives of this paper are to simultaneously improve power system damping and to maintain voltage at the static var compensator (SVC) location bus simultaneously.
      
The ideas of adaptive nonlinear damping and changing supply functions were used to counteract the effects of parameter and nonlinear uncertainties, unmodeled dynamics and unknown bounded disturbances.

In this article, we propose the concept of a region of resonant speed to be applied to vibration of lightly damped multi-degree-of-freedom systems. This concept is an extension of the concept of peak amplitude speed of single-degree-of-freedom systems. Also, the concept of conditional resonance spell may be introduced. For the general systems with moderate damping, we must study the influence function in the time region or the transfer function in the frequency region, and here a discussion of the concept...

In this article, we propose the concept of a region of resonant speed to be applied to vibration of lightly damped multi-degree-of-freedom systems. This concept is an extension of the concept of peak amplitude speed of single-degree-of-freedom systems. Also, the concept of conditional resonance spell may be introduced. For the general systems with moderate damping, we must study the influence function in the time region or the transfer function in the frequency region, and here a discussion of the concept of resonance is of no significance.In this article, we also briefly discuss the relation between the width of the resonance speed region and the combination of the different exciting forces.

本文提出对于轻阻尼多自由度系统,可以自然地把单自由度系统峰值振幅转速的概念推广为共振转速区的概念。作为近似判断,可使用条件共振转速。对于一般阻尼较大的系统,宜于讨论时间域中的影响函数或频率域中的传递函数,讨论共振转速等概念是无益的。本文还简单地讨论了共振转速区宽度和激振力配置间关系的计算方法。

This paper proves one to one correspondence single value function relationship between critical frequency of a torsional system of three disks and its damping by mathematical means.On the basis of this relationship we propose the resonance method to take measure of the damping of viscous-shear damper. The method has been proved right many times by experiments in the practical system which the paper introduces.

本文用数学方法证明了三圆盘扭振系统的共振频率与阻尼之间的一一对应单值函数关系。在此基础上,提出了测定硅油减振器阻尼的共振法。此方法已在本文所介绍的实际系统中多次由实验结果所证实。 阻尼是影响硅油减振器特性的最重要的因素。用通常的方法很难测定它的阻尼。但是共振法能在不破坏硅油减振器的条件下,经济,方便,快速的测定它的阻尼,所以我们认为共振法在生产中是有重要意义的。

A method, by taking the difference between two mean rotative moments, is applied hereon to analyze the synchronous vibration on a self-synchronous vibrating machine with single or duaI mass in space motion. Such an analysis has been considered with the addition of following aspects:1. Synchronization conditions in a self synchronous vibrating machine;2 Damping effects on the synchronization conditions and the stability of synchronous working state.3. Influence of the moment discrepancy between two vibrating motors (△Mg) and the frictional moment discrepancy betweey two rotating shafts (4△Mf) on the working state of vibrating machine.A synchronization criterion has been developedas:where Dα: synchronization factor;W: stability factor; m0,r: eccentric mass and its eccentricity;κ: angular velocity.Also, the stability criterion of synchronous state has been given in the term of respectively. The symbol △α0 here expresses the phase angle between two eccentric masses. The stability factors W of a self-synchronous vibrating machine, in space motion, are given by formula(21)and (54) as working with single mass and dual mass respectively. Fairly satisfactory results have been achieved by the experimental verification for the above.

本文用平均转矩差法研究了空间单质体与双质体自同步振动机的同步理论,对下列问题予以考虑: 1.自同步振动机的同步性条件; 2.振动阻尼对振动机同步性条件与同步运转状态稳定性的影响; 3.两电动机转矩差(△Mg)与两转轴上的摩擦转矩差(△M_f)对振动机工作的影响。 求得同步性判据为 |D_a|≥1,D_a=m_0~2φ~2r~2W/△M_g-△M_f 式中,D_a——同步性指数; W——稳定性指数; m_0、r——偏心质量及其偏心距; φ——角速度。 并求得同步运转状态的稳定性判据为 Wcos△α_0≥0 即 W≥0 (当△a_0=-90°~90°) W≤0 (当△α_0=90°~270°) △α_0为两偏心质量的相位差角。 自同步振动机的稳定性指数W,当振动机为空间单质体和空间双质体时其表达式分别为式(21)及式(54)。上述判别式通过实验验证,结果是满意的。
