A method to find the optimized parameter values of passive dynamic walking biped is presented. The effects of biped physical parameters on the stability property of passive gaits are studied by simulation experiments. The chosen parameters include the mass distribution
length of leg and slope angle. The stability property of passive walking limit cycles is used as criterion of optimization calculation
including the orbital stability described by eigen-values of linearized Poincare map and the global property described by size of attraction region. The simulation results show how the stability of limit cycle varies when physical parameters of the passive biped change. The work is useful to explore the inherent property of passive dynamic walking and can be used as an important instruction in the mechanical design of biped robots based on principle of passive dynamic walking.

The solar irradiance monitor (SIM)
with the design accuracy of 5
used to monitor the secular changes of the total solar irradiance on FY-3 satellite
takes the sun-scanning measurement method on-orbit. Compared to the sun-tracking measurement method
this method simplifies the structure and cuts the cost
but the measuring accuracy is affected by the sun-synchronous orbit
sunlight incidence angle and the installing angle of the SIM in the satellite. Through the ground calibration experiment
studies on the affection of different sunlight incidence angles to the measurement accuracy. First
by the satellite tool kit (STK) simulation software
simulates the orbital parameters of the sun-synchronous satellite
and calculates the Sun ascension and declination at any time. By the orbit coordinate transformation matrix gets the components of the Sun vectors to the axes of the satellite
and base on the components designs the field of view and the installing angles of the SIM. Then
designs and completes the calibration experiment to calibrate the affection of the incidence angles. Selecting 11 different angles between the sunlight and the satellite X-axis
measures the total solar irradiance by the SIM at each angle
and compares to the irradiances of the SIAR reference radiometers
and gets the coefficient curves of the three channels of the SIM. Finally
by the quadratic fitting
gets the correction equations on the incidence angles: R 1=5.7110-52 -2.45310 -3+1.0302
R2=2.8410-5-1. 96510-3+1.0314 and R3 =1.7210 -52-4.18410-4+0.9946. The equations will aimprove the on-orbit measurement accuracy of the solar irradiance
and are very important to the on-orbit data processing after the satellite launched. 2011 SPIE.
