Synthesis of trigonometric motion programs with lower motion characteristics [PDF]
Mechanical Sciences, 2022 Motion characteristics are dimensionless peak values of velocity, acceleration, jerk, and acceleration multiplied by velocity of a motion program. In general, these peak values of synthesized motion programs should be as low as possible.
