Permanent magnet synchronous motor (PMSM) servo
drive system has been widely used for industrial sewing
machines. The conventional control method is PID, which has
some disadvantages such as large overshoot, bad robustness. In
this paper, a servo control of the industrial sewing machine
system based on the active disturbance rejection control (ADRC)
is proposed, which can arrange the transient process, estimate
and compensate the uncertain internal and external disturbance.
It can highly enhance the dynamic performances of the system.
Based on the Matlab/simulink software, the simulation results of
the industrial sewing machine control system proved the
effectiveness and robustness of the ADRC control strategy.
With the rapid development of the world textile industry,
the research on industrial sewing machines have been focused
on higher precision, more energy-saving, lower cost, higher
speed, multiple-function, more intelligence. In order to
achieve all these performance indexes, the main problem is to
develop an effective servo system. And the PMSM based
servo systems have attracted more and more researchers, for
which has several inherent advantages compared with other
types electric machinery, such as high power density, high
power factor, high torque to current ratio, high efficiency, low
inertia, rugged construction, easy for maintenance and so
on[1,2].
The PID control is one of the early developed control
strategies. Due to its simple algorithm, good robustness and
reliability, it has been widely used to design position, speed
and electric current loop controller in industrial sewing
machine servo system. Sewing machine shops in chennai And classic PID control based, such as
increment PI control, fuzzy PID control, Neural PID control ,
multi-segment PI control are also adopted[3,4]. However, the
classical control strategies have some disadvantages, such as,
large overshoot, long adjustment time and so on. It is difficult
for the PMSM servo system to realize high precision control.
PMSM servo system is a typical non-linear time-variant
control system.
Many intelligent control methods such as
fuzzy control, self-adaptive control, neural network control,
sliding mode variable structure control, genetic algorithm
control are adopted to solve the problems. Many scholars have
done a lot of meaningful researches on these control methods
[5,6]. But it still has some difficult to realize.
The ADRC can not only arrange the transient process, but
also estimate and compensate the total disturbances on the
system, which can highly improved the performance of the
PMSM servo system. In this paper, ADRC is used as a speed
loop regulator in the industrial sewing machine servo control
system[7,8]. https://vssewingmachine.in/ https://vssewingmachine.in/ Simulation results indicated that, compared with
conventional PID control servo system, the proposed control
method has better dynamic performance, and stronger
robustness to the system disturbance.
In this paper, servo control of the industrial sewing
machine system based on the ADRC is proposed. Compared
with the conventional PID control, it can estimate and
compensate the uncertain load torque disturbance caused by
the external and internal of the system, which can highly
enhance the robustness of the system. Simulation results have
proved the effectiveness and feasibility of the ADRC, and the
control system has better dynamic performance and
robustness.
