13877-hared-pdf-Datasheet-IDG650.rar - The IDG-650 is an integrated dual-axis angular rate
sensor (gyroscope). It uses InvenSense’s proprietary and
patented MEMS technology with vertically driven,
vibrating masses to make a functionally complete, lowcost,
dual-axis angular rate sensor. All required
electronics are integrated onto a single chip with the
sensor.
The IDG-650 gyro uses two sensor elements with novel
vibrating dual-mass bulk silicon configurations that sense
the rate of rotation about the X- and Y-axis (in-plane
sensing). This results in a unique, integrated dual-axis
gyro with guaranteed-by-design vibration rejection and
high cross-axis isolation. It is specifically designed for
demanding consumer applications requiring low cost,
small size and high performance.,2010-12-29 16:26:51,下载10次
MMA7361L.rar - The MMA7361L is a low power, low profile capacitive micromachined
accelerometer featuring signal conditioning, a 1-pole low pass filter,
temperature compensation, self test, 0g-Detect which detects linear freefall,
and g-Select which allows for the selection between 2 sensitivities. Zero-g
offset and sensitivity are factory set and require no external devices. The
MMA7361L includes a Sleep Mode that makes it ideal for handheld battery
powered electronics.,2010-12-29 16:26:03,下载3次
imustabilizer_090219.zip - (UAV) has grown rapidly over the past decade. UAV applications
range from purely scientific over civil to military. Technical
advances in sensor and signal processing technologies enable
the design of light weight and economic airborne platforms.
This paper presents a complete mechatronic design process
of a quadrotor UAV, including mechanical design, modeling
of quadrotor and actuator dynamics and attitude stabilization
control. Robust attitude estimation is achieved by fusion of lowcost
MEMS accelerometer and gyroscope signals with a Kalman
filter. Experiments with a gimbal mounted quadrotor testbed
allow a quantitative analysis and comparision of the PID and
Integral-Backstepping (IB) controller design for attitude stabilization
with respect to reference signal tracking, disturbance
rejection and robustness.,2010-12-29 16:24:32,下载96次
Quadrocoptersikiric_vedran_08027_2.rar - A simple low cost AFV solution would provide an attractive alternative to several
civilian applications where a helicopter would traditionally be used. Practical applications
could include: traffic surveillance, aiding search and rescue operations, looking out for
forest fires, etc.
The objective of this thesis is to build and experiment with a low cost prototype AFV.
This involves constructing a vehicle control system, as well as evaluating various design
features and building materials.
The vehicle will be propelled using four motors and propellers mounted to a fuselage.
The design details will be discussed more extensively later in the thesis,2010-12-29 16:16:24,下载4次
PID-without-a-PhD.rar - At work, I am one of three designated
“servo guys,” and the only
one who implements control
loops in software. As a result, I often
have occasion to design digital
control loops for various projects.
I have found that while there
certainly are control problems
that require all the expertise I can
bring to bear, a great number of
control problems can be solved
with simple controllers, without
resorting to any control theory
