“…Over the past few years, increased attention has been paid to the adaptive control of robotic systems with high degrees of freedom, with many research works developed based on the approach, including those in Chen (2015), Zhao et al (2016), Liu et al (2016), Andaluz et al (2012), Xing-Gang et al (2014) and Karray and Feki (2014). This is due to the fact that this type of robotic system can be implemented in complex applications with unknown parameters.…”
