RISNonminimum-Phase-Based Loop Shaping for Multimode Active Damping Control: Application to Piezoelectric Nanopositioning System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Piezoelectric nanopositioning systems, typically guided by flexure mechanisms, are limited by lightly damped resonances, which constrain achievable closed-loop bandwidth. Active damping controllers (ADCs) are ...
