1. Expert experience and fuzzy control
for high-efficient feed pelleting
By Bob Chen, March 13, 2013

2. Background Solutions Benefits
However, all know,
As we
human experience and operations are more flexible
fully automatic production is the future
in the of feed manufacturing industry because of following advantages:
optimization of production to gain satisfied results.
For example, in Increased output and enhanced productivity
a feed mill producing pig feed pellet
 The automationspeed ofis able to run a pellet mill stably at a feeding rate of 57Hz;
system production, showdown time
 Improved and uniform quality
 But a skillful operator is able to run the same pellet mill at a feeding rate of 60Hz;
consistent and stable production
 After that, switch the system from Manual to Auto, it fails to feed at 60Hz.
 Reduced cost and fewer accidents
That means 57Hz is the current optimal control strategy of the control system.
……
manpower, human influence
Is there any possibility of an automatic control system acting like
an experienced pellet mill operator? How?

3. Background Solutions Benefits
How Muyang solve these problems?
To link expert experience with intelligent
and reliable automation
Realizable method:
Fuzzy control
A fuzzy control system is based on fuzzy logic, it is characterized by:
 be able to learn from expert experience rules;
 be easily upgraded by adding new rules to improve performance or add new
features;
 more effective control with low-cost implementations because of simple
hardware configuration.
