Control of impact angle can considerably increase missile's lethality. However, large impact angle will lead to large lateral acceleration requirement during the flight. In order to avoid command saturation, one can choose initial heading angle to decrease the magnitude of the guidance command. Based on impact angle control optimal guidance law of air-to-surface missile, some more in-depth research...
This paper proposes an assist-handle for manual conveyance of flexible part and its semi-active operation assist control. The assist-handle consists of a handle, a variable damper and a mechanical spring. The variable damper and the mechanical spring are connected in parallel. The assist-handle can be attached to a general hand cart, through which a human operates the hand cart. In order to suppress...
Distributed diesel generation is still widely used to supply electric power in a variety of applications. These applications range from backup power supply systems and combined wind-diesel generation to providing power in places where grid connection is either technically impractical or financially uneconomic. Due to the ever increasing cost of diesel fuel and the environmental issues associated with...
This paper presents an optimal controller for an Instantaneously Coupled System (ICS) which was designed by coordinating multiple lower-dimensional optimal controllers. We augmented subsystems of the ICS with coordination variables, and then used value functions to coordinate the augmented subsystems by managing tradeoffs of the coordination variables. We apply this method to humanoid walking and...
In the area of fuzzy control for civil structures, how to generate fuzzy rules for structural vibration control is a key issue. In this paper, a dynamic fuzzy neural network (DFNN) algorithm is adopted to extract fuzzy rules based on the sample data obtained from the performance of the system under optimal control algorithm. First, the structure and algorithm of DFNN is introduced. Then, a fuzzy controller...
Some difficult problems in engineering was not completed because of restrictions on freedom of the fixed components of mechanism. With the parameter analytical method, a controllable multi-DOF manipulator model was defined on the basis of spatial closed link mechanism. The analysis of kinematics was done and the parameters of its trajectory was intelligently optimized by MATLAB, in order to achieve...
In this paper, locomotion of a capsule robot which is also called the Capsubot is studied. The Capsulbot is two-mass system and it moves with no external parts. In the previous our researches for the Capsubot, we have studied to find a proper control input through an optimal control and verified by simulations and experiments. The previous study for the Capsubot, however, was totally based on open-loop...
PN (proportional navigation) law is in wide use. In this paper, the traditional proportional navigation control system is analyzed, then we find that the traditional proportional navigation guidance law is sensitive to the time-to-go (i.e., time to interception) measurement, in other words, the time-to-go estimation error may cause significant degradation in the performance of the PN guidance law...
