As a MEMS sensor working in the force feedback capacitive accelerometer system, the sensing mass of MEMS sensor is driven by the external acceleration, the differential modulating pulse voltage and the preload voltage. Under high preload voltage, the common servo loop design method of the capacitive MEMS accelerometer is invalid since the open loop system features can't be obtained by experiments...
Based on integrating the property of sliding mode control (SMC) with the thought of variable universe in adaptive fuzzy controller, a design method of variable universe fuzzy self-learning sliding mode control (FSSMC) is proposed. By adjusting the universes of input variables and the membership functions of conclusion part in rules on-line, the high frequency chattering in the control input caused...
The position tracking control of a missile electrohydraulic servo mechanism is studied. Since the dynamics of the system are highly nonlinear and have large extent of model uncertainties, such as big changes in load and parameters, a design method of adaptive fuzzy sliding mode control is presented. The adaptive fuzzy controller is introduced to approach the equivalent control of sliding mode control,...
