This paper deals with the yaw channel guidance of the launch vehicle in detail by means of the idea of predictive guidance. The basic principle of perturbative and predictive guidance are described. Under the conditions of both navigation computation and perturbative measurement the basic calculative formula of the perturbative and predictive guidance is derived and the simplified form of the predictive guidance and its requirements for the simplification are discussed.

This paper deals with the yaw channel guidance of the launch vehicle in detail by means of the idea of predictive guidance. The basic principle of perturbative and predictive guidance are described. Under the conditions of both navigation computation and perturbative measurement the basic calculative formula of the perturbative and predictive guidance is derived and the simplified form of the predictive guidance and its requirements for the simplification are discussed. Besides, we also suggest the concept of "zero control and unbias states" and the problem of optimal control guiding to the zero control and unbias states. A closeloop solution of optimal control was derived. The concept and results are to be researched further.

This paper is concerned with the sequential control principle of an active acquisition system of gravity-gradient stabilized satellite with minimum hardware. In this system yaw sensors are not used and the velocity damping is realized effectively by using Logical circuits to process infrared horizon sensor's information, therefore, the expensive feedback packages are saved. Computation results show that this kind of control system is very powerful in adapting to launch vehicle and gas jet actuator with eccentric thrust. It is possible to get much higher acquisition accuracy by reasonable choice of system parameters. Unlike the traditional acquisition methods, a new acquisition concept is proposed in the paper.

In this paper, A path adaptive guidance method (iterative guidance method) for solving the control problem about that A launch vehicle flies in minimum time is presented. This method obtained by means of the optimal control theory can attain guidance condition in space. Main conceptions and results of the method are described. The approximate optimal guidance formulas and an iterative guidance model used for launching earth's satellites are introduced. Then its operative program and guidance accuracy got with the help of analogue calculation are also shown. The accuracy is much higher than that of Delta minimum. Thus it is a new method which can be widely used in guiding launch vehicle.
