The piezoelectric actuator (PEA) is commonly used in the micro-nano precision positioning. However, PEA exhibits nonlinearities, such as hysteresis, saturation, and creep. Also, together with the actuated stage, mechanical and electrical dynamics exist. For ultra high precision and fast response positioning control, all those dynamics and nonlinearities have to be taken into account. In this paper,...
Commercial-off-the-shelf electronic components (COTS) offer a very low cost and attractive solution for construction of electronic systems for Mars missions, including the actuator electronic systems for the Mars Rovers. One issue with using COTS lies in the difference between their specified operating temperature range (-55/spl deg/C to125/spl deg/C for military components) and the temperatures observed...
