2 If your teeth chatter, they knock together repeatedly because you are very cold or frightened:
In this paper a new method of suppressing chattering is presented.
Note also that the dual self-motion continues for a relatively long period of time during which a chattering-type behavior is observed.
However, they needed a supervisory controller-like component in the control input, which is basically a discrete switching function and may cause unnecessary chattering.
Although the chattering effect is obvious, its amplitude is small due to the used bounds.
Therefore, double cutting action and chattering reduction can be achieved simultaneously.
Furthermore, the "second order" interest consists in the reduction of chattering phenomenon.
The approach to proposed robot control involves using a neural network feedforward loop together with a discrete time 'chattering-free' feedback loop.
Although the acceleration error converges to zero under the steady state conditions, chattering appears because the sign(s) function is involved in the control input.
