针对两轴两框架光电平台电机存在的非线性以及方位与俯仰轴系之间互相影响产生的耦合对控制精度的影响,提出一种基于逆系统的光电平台非线性解耦控制方法.根据两轴光电平台方位与俯仰框架的动力学模型,建立状态空间方程,然后设计逆系统,获取系统的状态变量,并将逆系统与原系统进行串联得到一个伪线性系统,使原来的单个耦合非线性多输入多输出系统转换为两个线性解耦单输入单输出子系统,以消除方位俯仰轴系之间存在的非线性强耦合.在Matlab中建立系统仿真平台,仿真结果表明,所设计的基于逆系统的光电平台非线性解耦方法可以有效减小方
The tumor microenvironment features over-expressed hydrogen peroxide (H2O2).Thus,versatile therapeutic strategies based on H2O2 as a reaction substrate to generate hydroxyl radical (·OH) have been used as a prospective therapeutic method to boost anticanc
Composite materials have elicited much inter-est because of their superior performance in the removal of toxic and radioactive uranyl ions from aqueous solutions.With polyethyleneimine as a functional group,carboxy-lated chitosan as a matrix,and oxidizing
Chemical industry is always seeking opportu-nities to efficiently and economically convert raw materials to commodity chemicals and higher value-added chemical-based products.The life cycles of chemical products involve the procedures of conceptual produc
Alkylation of benzene to value-added,high octane number and low toxic toluene and xylenes provides a way to lower benzene content in gasoline pool,and is hence a method to promote fuel quality.On the other hand,CO2 accumulation in the atmosphere causes gl
Production cost,capacitance,and electrode materials safety are the key factors to be concerned about for supercapacitors.In this work,a type of carbon nanosheets was produced through the carbonization of tripotassium citrate monohydrate and nitric acidifi
Advanced model-based control strategies,e.g.,model predictive control,can offer superior control of key process variables for multiple-input multiple-output sys-tems.The quality of the system model is critical to controller performance and should adequate
To study the dynamic behavior of a process,time-resolved data are collected at different time instants during each of a series of experiments,which are usually designed with the design of experiments or the design of dynamic experiments methodologies.For
The catalytic hydrogenation of carboxylic acid to alcohols is one of the important strategies for the conversion of biomass.Herein,a series of Ni-doped PtSn catalysts were prepared,characterized and studied in the hydrogenation of acetic acid.The Ni dopan
Solvent-based post-combustion capture tech-nologies have great potential for CO2 mitigation in traditional coal-fired power plants.Modelling and simula-tion provide a low-cost opportunity to evaluate perfor-mances and guide flexible operation.Composed by
