Description: (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.

Description: The open source project DSP_INS is an inertial navigation system on the TI DSP
platform TMS320F28335 with MEMS inertial sensors and commercial GPS module. Inertial
sensors are actually used only for estimating attitude, heading and velocity.
Position information totally comes from GPS (see Q2 in FAQ part). Currently the
MEMS IMU (Inertial Measurement Unit) ADIS16355 and GPS module u-blox LEA-5H
are supported. DSP_INS also reads magnetic field data from HONEYWELL HMC1051/1052.
You can also use the latest IMU module ADIS16405, which also contains magnetic field
sensors.
There is a 10-order extended Kalman filter in DSP_INS, which takes angular velocity,
acceleration, magnetic field, and GPS velocity as inputs. It provides outputs
including angular velocity, acceleration, attitude, heading, velocity, and position
(from GPS) every 10 milliseconds. DSP_INS is proved to be effective and reliable in
several robot and UAV projects.

Description: Altitude location for UAV by using federated filter
is discussed, the fourth structure is selected, because its two
sub-filters involving altitude sensor and the difference Global
Positioning System (d-GPS) respectively are fully isolated from
each other and thus make the federated filter more fault-tolerant
and better in real-time performance. Data fusion based on this
federated filter was simulated. When the d-GPS is working
normally and simulation results show that values estimated by
data fusion base on federated filter are very close to real values
and the variance of federated filter converges to 10m. When the
electromagnetic environment is very bad, as is usually the case in
war zone, the d-GPS is silent for a long time, variance based on
federated filter converges to 13m, bigger than the 10m.
Compared with previous paper variance based on Kalman
converges to 15m, higher than the 13m. Federated filter can give
much more accurate estimation than Kalman filter.

1)避免重新实现大多数项目共有的功能，例如:
-离散化策略(例如欧拉向前，龙格库塔，…)
-系统线性化的雅可比计算方法，例如基于符号或样本的方法
-实施标准车辆动力学，如独轮车或类似无人机的车辆，并实施不同的姿态表示，如旋转矩阵或四元数
-状态观测器自动生成，例如扩展卡尔曼滤波器(EKF)
-基于网络的控制器的实施结构

1) Avoid re implementing features common to most projects, such as:
-Discretization strategies (e.g. Euler forward, longkutta,...) )
-Jacobian calculation methods for system linearization, such as symbol based or sample based methods
-Implement standard vehicle dynamics, such as wheelbarrow or similar UAV vehicles, and implement different attitude representations, such as rotation matrix or quaternion
-Automatic generation of state observers, such as extended Kalman filter (EKF)
-Implementation structure of network-based controller
-...
2) Establish a common set of interfaces that allow independent design and integration of different components (e.g., vehicle models, controllers, sensors, viewers,...) and implement a reusable / transparent / easy to debug programming style.)
