Abstract-One of the gunboat weapons that need to stay stable is the cannon. Its unbalance position that caused by pitch and roll disturbance will influence the target accuracy, target detection, tracking system, object identification and the ability to counter the threat. In order to determine this disturbance, the balancing control on the movement platform can be solved by using neural network control and sliding mode control methods. To make an approach, the cannon movement system can be modeled in training and elevation movements and the disturbances are modeled through pitch and roll mechanisms. The variations in obtained parameters of training and elevation (moment of inertia) are the non-linearity result of the moving cannon. The system is simulated to verify the error in the controller's output processed using the neural network coordination system control and sliding mode control. The learning process in the neural network is made using back propagation method in order to get the weight value at the different disturbances which their results are given in the simulation of coordination models. On the other hand, the free chattering of sliding mode control is implemented in order to make the movement of training and elevation can be controlled for having the desired angle position in the disturbance of pitch and roll. This paper is based on the study to compare the performance of neural network control and sliding mode control on the moving platform.Index Terms-Cannon barrel, elevation and training, neural network control, pitch and roll, sliding mode control.

“…Although modular armature segments technology can provide some benefits, it does face some unique challenges such as the movement on multiple stators [4]. Reference [5] discusses the special transition problems in a linear induction launcher by a lumped-parameter circuit model and a mesh-matrix method.…”

“…This topology consists of the active part and the inactive part, so the mover is reaccelerated and decelerated repeatedly. Considering operational controllability, in our laboratory the segmented linear motor has continuous iron core and multi-segmented divided winding, which is similar to the system of M-Bahn in Germany [4]. In this paper we describe the fabrication techniques of a downsized multi-segmented plate linear launcher.…”

This paper presents a detailed description of downsized multi-segmented plate permanent magnet linear launcher, which puts emphasis on modular stator structure. For multi-segmented stator launcher with concentrated winding, specific topology and slot/pole number combinations are discussed. Considering different end boundary, back electromotive force (EMF) and inductance parameter of the starting and middle segments are investigated by finite element method (FEM), and then the accuracy of numerical solutions are verified by experimental results. Based on parameters characteristics analysis at transition, dynamic electromagnetic thrust is evaluated by energy method. Finally the combined simulated model with currents tracking scheme is built for multisegmented system.

“…However, a discontinuous arrangement may be adopted in long-distance systems unless constantspeed requirements are very strict. Thus, our laboratory has proposed a discontinuous primary LSM with the primary side provided only when accelerated/decelerated operation is necessary, instead of constant application of thrust [2]. Figure 1 shows a comparison between the drive patterns of such a discontinuous primary design and the conventional continuous primary design.…”

Constant load angle control of discontinuous primary linear synchronous motor without position feedback

et al. 2005

View full text Add to dashboard Cite

SUMMARYPermanent magnet linear synchronous motors (PM-LSM) that are utilized for the discontinuous primary have been proposed to satisfy the requirements include speeding up the transportation system and simplifying the maintenance as a result, synchronization and a positioning method are established. However, velocity pulsation of the secondary occurs when the secondary mover overlaps with the primary section. This paper describes the examination of constant load angle control without position feedback with the aim to suppress the velocity pulsation, which occurs in the re-acceleration part.
