Loss-function optimal control of the positioning servomotors with static torque proportional to the speed
- Trang 232-235
The maximum efficiency use of industrial purpose equipment is an actual concern
imposed by the necessity of increasing the productivity of all the equipment and
reducing the energy consumption. Taking into account this trend, in the present
paper, the authors try to determine the optimal control law of the positioning
an open-loop servo system with static torque proportional to the speed so that
t...

Precise torque and speed control in pure electric braking operation of AC traction in low speed range
- Trang 142-147
This paper describes a method to achieve precise torque and speed control of AC
traction in low speed range. The authors apply an instantaneous speed observer
to improve the speed information and propose a new pole assignment by analysis
in multirate-discrete-time domain. Validity of this method is verified though
various simulations.

H/sup /spl infin// control of permanent magnet linear synchronous motor based on neural network command-compensator
- Trang 194-196
This paper presents a robust speed controller for PMLSM based on H/sup /spl
infin// control theory. A command-compensator based on neural network is
proposed to compensate the disturbances of the system. Simulation and experiment
results show that the control strategy proposed in this paper is feasible. H/sup
/spl infin// speed controller can make the direct drive system have strong
robustness to ...

Position and force control of flexible manipulator with position sensitive device
- Trang 414-419
This paper presents a position and force control of a flexible manipulator with
PSD (position sensitive device). If this method is used, the arm approaches an
object exactly, and pushes it by a desired force although the object is unknown.
The position control is based on the resonance ratio control, When the reaction
torque is estimated by the reaction torque observer, a friction model is used in...

Seek control of hard disk drives based on final-state control taking account of the frequency components and the magnitude of control input
- Trang 40-45
In this paper, the authors develop a new design method of the reference
trajectory for hard disk drives. The control input is assumed to be generated
through zero-order-hold and the reference trajectory is designed so that the
frequency component of the control input is minimized over the desired frequency
points. Input constraints can also be incorporated into the design. Simulation
results are s...

A wheelchair type mobile robot taking environmental disturbance into account
- Trang 500-505
Both human and robot will carry out a task which is not realizable by only each
of them. In particular, a human recognizes environment and reflects to
trajectory planning well. On the other hand, the robot generates the controlled
force more than a human. In this paper, the best combination of human ability
and robot capacity is considered. Based on the force commands from a human, a
robot support...

Line-of-sight constrained exploration for reactive multiagent robotic teams
- Trang 455-461
This paper reports on an investigation into how a team of robotic agents can
self-organize for the exploration of a building, subject to the constraint of
maintaining line-of-sight communications. Three different behavioral strategies
(anchored wander, quadrant-biased anchored wander, and informed exploration)
have been developed and tested in simulation. The results are demonstrated
within the co...

Vectorial torque control of permanent magnet AC (PMAC) machine drives in field weakening region
- Trang 257-262
A novel approach to the torque control both in constant torque region, and in
the field-weakening one of permanent magnet AC machines drives fed by VSI, is
described in this paper. It is based on the prediction of all the possible
transient responses of the drive, in terms of torque and flux, to the available
output voltages of the voltage source inverter feeding the motor. Experimental
results co...

Limitations in control of elastic servos with co-located sensors
- Trang 92-97
Performance limitations of elastic servomechanisms where only the motor position
is measured emerge considering also the load position behavior. Limitations
inherent to PID control, the most common solution in commercial products are
dealt with first. The authors explicitly relate a bound of the H/sub /spl
infin// norm of the motor position setpoint to load position transfer function
to the motor ...
