简介：这份报纸为机器人考虑转矩控制问题，灵活关节由电的致动器开车。用PI转矩控制器的可完成的靠近环的追踪带宽可能由于零由负担动力学介绍了的传播是有限的，这被显示出。这限制被与PI转矩控制器在一致从负担运动使用积极反馈克服。积极反馈以负担速度，加速和猛拉被给。稳定性调节因为设计分散的PI转矩控制器以Routh-Hurwitz标准被导出。封闭系统的骚乱拒绝性质被描绘，分析被执行由省略加速或猛拉信号调查近似积极反馈的使用。这份报纸的结果为二DoF(自由的度)被说明系统。一个DoF系统的试验性的结果也被包括。

简介：机电的致动器广泛地在许多工业应用被使用。通常有一些限制，在一个设计系统存在。这份报纸建议一个简单方法为机电的致动器设计抑制控制器。控制器合并在内部模型控制利用的想法并且为预兆的控制建模。他们与统一用标准控制系统结构被设计否定反馈。控制器的结构象设计过程一样相对简单。处理机制的输出限制基于许多时间向前走的控制植物行为的预言。机制增加控制控制植物的性能和安全。建议控制器提供的好处在在二个机电的致动器的控制系统执行的真实实验被表明了：一台DC马达和一个electrohydraulic致动器。
