TY - JOUR IS - 6 VL - 7 PB - IEEE EP - 656 N2 - For robotic systems tracking a given geometric path, the paper addresses the problem of satisfying input and state constraints. According to a prediction of the evolution of the robot from the current state, a discrete-time device called a path governor generates online a suitable time-parameterization of the path to be tracked, by solving at fixed intervals a constrained scalar look-ahead optimization problem. Higher level switching commands are also taken into account by simply associating a different optimization criterion to each mode of operation. Experimental results are reported for a three-degree-of-freedom PUMA 560 manipulator subject to absolute position error, Cartesian velocity, and motor voltage constraints KW - Acceleration; Error correction; Feedback; Motion control; Motion planning; Robot control; Robot motion; Torque; Trajectory; Voltage JF - IEEE Transactions on Control Systems Technology Y1 - 1999/11// A1 - Bemporad, Alberto A1 - Tarn, Tzyh-Jong A1 - Xi, Ning UR - http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=799665&isnumber=17379 TI - Predictive path parameterization for constrained robot control SN - 1063-6536 AV - none ID - eprints496 SP - 648 ER -
