- Description
- This paper explores the concept of dual-stage actuators in order to reduce the errors generated by output quantization in motion systems. Oscillations are induced upon the quantized actuator such that its trajectory is reconstructible by a model-free estimator. Based on the nature of these oscillations and on intermittent measurements that indicate when the output crossed from one quantization region to another, the exact value of the actuator output is computed. The micro actuator is then used to compensate the error generated by these oscillations and achieve an improved steady-state response. Simulation results show a promising perspective for the proposed approach.
