Abstract
This paper illustrates the application of an indirect adaptive trajectory controller for MEMS lateral comb resonators to obtain better convergence and trajectory performance. A recursive least square estimator with forgetting factor is used to estimate the parameters of MEMS in real-time. Accordingly, the control law and gains are derived to achieve high performance trajectory controls. Simulation results demonstrate a close trajectory profile and accurate parameter estimation performance.
