Operational Space Control Under Actuator Bandwidth Limitation

Hosang Lee,Jaeheung Park,Hosang Lee,Jaeheung Park

The actuator bandwidth limitation deteriorates the stability and performance of torque-based robot controllers. Operational space control is especially prone to this problem, since the limited bandwidth of a single actuator can reduce the performance of all related tasks simultaneously. In this article, an intuitive way to penalize low performance actuators is proposed to improve the performance o...
