This paper presents a new reentry guidance algorithm for RLV (Reusable Launching Vehicle). The algorithm consists of two integrated components: trajectory planning algorithm and tracking algorithm. The most striking feature of algorithm here lies in that both planning and tracking are executed directly in height-velocity space
which is different from the methodology of configuration of drag in traditional shuttle guidance. In the session of trajectory planning
all trajectory constraints can be expressed with upper bound and lower bound in height-velocity space
then a linear interpolation is carried to search the nominal trajectory satisfying the requirement of downrange and target constraints. Then the tracking algorithm uses feedback linearization method to track this nominal profile and meet all constraints. Another typical feature of this algorithm is the strategy of downrange extension using FPA (flight path angle) controller to fulfill the requirement of large downrange. Proper combination of planning-tracking algorithm and FPA controller can bring great flexibility and adaptability to reentry guidance. The algorithm is proved to be robust enough to accommodate the model error and noises in the dynamics. 2011 IEEE.

A new servo control methods for O-E theodolite is presented in this paper. The methods integrates optimally feed forward and feedback control
and adopts acceleration delay compensation based on velocity delay compensation
then achieves servo control of O-E theodolite effectively. Furthermore
Angular acceleration sensor is applied as information resources
and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite
the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods
this servo control methods can improve significantly tracking precision and stability of O-E theodolite. 2010 IEEE.

A nonlinear control strategy for controlling a motion system with mechanical resonance is presented in this paper. A mathematical model of the servo system is derived according to the parameters of an actual system. By using two Tracking-Differentiators
reference input and system output are tracked and their differential signals are given simultaneously. A nonlinear PD control law in velocity loop is designed based on non-smooth feedback. The simulation results show that the control law is superior remarkably in performance to linear PD control law and the classical PID control law. Tracking-Differentiator resolves the contradiction between rapidity and overshoot of system response. The nonlinear PD control law improves system dynamic performance and intensifies the ability of disturbance rejection. The control design achieved in this paper makes the servo system more robust. 2010 IEEE.
