High Precision Over Long Range: A Macro-Micro Approach to Quantized Positioning Systems

This article proposes a macro-micro approach to deal with sensor quantization in positioning systems. First, a control strategy able to asymptotically drive the quantized (macro) actuator toward an oscillatory motion around the desired reference is presented. A microactuator is, then, added to compe...
