Unlike traditional command shapers, the proposed strategy matches the discrete command signal steps to the machine minimum time step of the control hardware used.
Considering the problems of parameter uncertainties and load disturbance appeared in induction motor drive systems, a discrete-time command filtered adaptive position tracking control method based on neural networks is proposed in this paper.
The method is illustrated by considering the conversion into discrete-time velocity commands of control schemes for redundant robots that minimize the (weighted and/or biased) norm of joint acceleration or joint torque.
Thus, only a few and discrete values of the commands can be sent and the solution space of every interstation is made up of a relatively small set of speed profiles.
Then, this information is automatically matched to the characteristics, discrete codes and infrared commands of the more than 225,000 devices from more than 5,000 manufacturers contained in Logitech's online database.
Rather than examine each of these facets individually, we aggregated them into an index using the polychoricpca principal components command for discrete variables using the Stata 10.1 statistical software program [ 36].
A comparative assessment between the discrete model inversion based on feedforward control and the command preshaping technique is presented.
This context requires a whole new set of concepts, methods, and tools that are adapted to capture the integration of logical commands, continuous time evolution, and discrete event dynamics.
With reference to robots that are redundant for a given task, we present a novel and intuitive approach allowing to define a discrete-time joint velocity command that shares the same characteristics of a second-order inverse differential scheme, with specified properties in terms of joint acceleration or torque.
Cooperative and coordinated control of reactive power resources can be realized in multiple modes, such as continuous or discrete mode, high speed or low speed mode and voltage command or reactive power command mode. .
