Precision Controls Laboratory (PCL)

Based at the University of Waterloo, the Precision Controls Laboratory (PCL) conducts research on design, modeling, and control of precision motion delivery systems. PCL focuses on the development of high-speed, high-accuracy tracking control laws, efficient and robust identification techniques for drive parameter estimation, and smooth trajectory planning algorithms for jerk-continuous spline interpolation and feed rate optimization.

PCL’s main research focuses on enabling the execution of complex movements in minimum time with highest accuracy, in multi-axis machines. Application areas for this research include high speed machine tools, robots, and electronic/semiconductor manufacturing equipment.
