The textual subject is from the psychology angle to set out, analyzing when the piano give musical performance to be subjected to easily where the influence of a few mental factors, how regulate these mental and unsteady motions which appear easily and think a way to overcome, make the performer understand and want to acquire to give musical performance goodly in addition to giving musical performance technique consummately, have to also have good mental character, the mental character of performer with give musical performance result to exist an inevitable relation therefore, should strengthen the mental character that the ego mental state of training the student regulates an ability and development student.

中文摘要：本文的主旨就是从心理学角度出发，分析在钢琴演奏时容易受哪几种心理因素的影响，如何去调节这些容易出现的心理不稳定情绪并想办法克服，使演奏者明白到要想获得良好的演奏除了要有精湛的演奏技巧外，还必须有良好的心理素质，演奏者的心理素质与演奏效果存在着必然的关系因此，应加强培养学生的自我心理调节能力与培养学生的心理素质。

The switching law is given out according to convex combination condition and the sufficient condition of the stabilization is obtained by switching among a finite number of controllers under the assumption that a single controller cannot make the systems stable and has H-infinity disturbance attenuation.
