本文研究了用于设定点调节的非最小相位线性标量系统的前馈最小时间平滑控制。目的是合成一个受输入及其导数非饱和约束的有界输入，直到达到预先指定的任意顺序。所提供的解决方案依赖于稳定的输入输出动态反演技术和输出转换函数的特设参数化系列。表现出驱动前和驱动后的合成最短时间输入是通过易于实现的封闭式表达式来确定的。举例说明了该方法。
The paper approaches the feedforward minimum-time smooth control of non-minimum-phase linear scalar systems for set-point regulation. The aim is to synthesize a bounded input subject to non-saturating constraints on the input and its derivatives till a prespecified arbitrary order. The provided solution relies on a stable input–output dynamic inversion technique and an ad hoc parameterized family of output transition functions. The synthesized minimum-time input that exhibits pre- and post-actuation is determined by means of easily-implementable closed-form expressions. Examples are given to illustrate the methodology.
