Designing a filament winding machine involves two major components. First component
is the designing of the mechanism which delivers appropriate winding pattern as
specified by the user (i.e. the winding angle). The second component is the realization of
an effective fiber tensioning system for ensuring consistent overall consolidation.
Today, there exist a variety of sophisticated methods to achieve both these parameters;
however the implementation of these techniques increases the price of a winding
machine, making its acquisition very difficult for small scale applications. Sophisticated
winding machine includes higher number of degrees of freedom, and high end CNC
controlled algorithms. However for creating axi-symetric products with constant
diameter, only a 2-axis winding is sufficient. On this note a novel cost effective method
for fiber winding angle control and fiber winding tension control is designed, simulated,
implemented into a low cost prototype 2-axis filament winding machine, and the scope
for its? further improvement has also been discussed.
The system designed, uses a cost effective PLC as the centralized controller of the system
for implementing both fiber winding control and tension control through PID control. A
novel actuator for tension control is designed and implemented.
Also a comparison between the conventional PI controller and a Mamdani type Fuzzy
inference based control system for controlling the fiber tension is made. In this process a
novel technique for making PI controller capable of handling known nonlinearities in the
system is introduced. Experimental system responses of the designed prototype are
analyzed.
