“…Trajectory tracking of the ball in the BP system is carried out using various fuzzy control techniques such as hierarchical fuzzy schemes (Fan et al, 2004), indirect hierarchical fuzzy cerebellar model articulation (Moreno-Armendariz, 2010), fuzzy adaptive integral controllers (Pattanapong and Deelertpaiboon, 2013), and interval type-2 fuzzy controllers (Farooq et al, 2013). Various nonlinear controllers like the back-stepping controller, recursive back-stepping controller, switching-driving Lyapunov function, SMC, and PID-SMC are designed by Ker et al (2007), Hongrui et al (2008), Casagrande et al (2009), Liu and Liang (2010), and Debono and Bugeja (2015), respectively. Likewise, various other control schemes such as stabilisation and control using mechatronic design principles, discrete lead compensator along with rapid prototyping, visual servoing control with an industrial robot manipulator as actuator, iterative control schemes with nilpotent approximation, pneumatic controllers along with touch screen and rotary cylinders, disturbance observer based friction compensation strategies, cascaded PD controllers tuned by particle swarm optimization (PSO), and model predictive controllers are used by Awtar et al (2002), Knuplez et al (2003), Park and Lee (2003), Oriolo and Vendittelli (2005), Yuan and Zhang (2010), Wang et al (2014), Roy et al (2014), and Oravec and Jadlovska (2015), respectively.…”
