8.9 The MEMS of Figure 8.29 is formed of two shuttle masses mi and m2 coupled by a serpentine spring of stiffness k and supported separately by two pairs of identical beam springs- each beam has a stiffness ki. The shuttle masses are subjected to viscous damping individually through substrate interaction-the damping coefficient is c, and an electrostatic force f acts on mi. Use a lumped-parameter model of this MEMS device and obtain a state-space model for it by considering...
