Decoupling control

The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

In this paper, a new method of system identification for a multivariable process is adopted to obtain system models from a pair of priori input/output data. Decoupling techniques are the suitable choice for most industrial processes wherein the interactions between process variables are significant.

In the two-coupled distillation column process, keeping the tray temperatures within a specified range around their steady state values assures the specifications for top and bottom product purity. The two-coupled distillation column is a 4 Input/4 Output process. Normally, control engineers decouple the process into four independent loops. They assign a PID controller to control each loop. Tuning of conventional PID controllers is very difficult when the process is subject to external unknown factors.

In this paper, an imitation learning approach for learning and generalizing grasping skills based on human demonstrations is presented. To this end, motions of robot hand (including finger, wrist, and elbow) with assumption that they are decoupled and each motion moves in two dimension space are investigated. Each element of the robot hand is modeled by an affine nonlinear equation and output of each motion ensure to track a prior trajectory.

In this paper we will build a timedependent diffusion equation that takes into account both spatial correlations and population control (fixed number of neutrons along generations). We will show that its solution obeys a traveling wave dynamic, and we will discuss the mechanism that explains this biasing of local tallies whenever leakage boundary conditions are applied to the system.

This article introduces a methodology of designing a wavelet operator suitable for multiscale modeling. The operator matrix transforms states of a multivariable system onto projection space. In addition, it imposes a specific structure on the system matrix in a multiscale environment. To be specific, the article deals with a diagonalizing transform that is useful for decoupled control of a system.

The decoupling control is a research field related to solving this problem, which has been studied by many authors in the past. This paper addresses to propose a new decoupling control method applied for two input two output processes (TITO) with multi-time delays. Simulation results show that the performance of the system is improved in the sense, that no longer interfering between the loops is occurred as well as the process output disturbances had been completely eliminated.

Decoupled flux and torque control of an induction machine can be realised by control of instantaneous phase current values, which in turn can be achieved by stator current space vector magnitude and position control with respect to the chosen flux space vector. As already discussed in the Section 2.3.3., a vector is composed of appropriate d-q axis components, d-axis component being the real part and qaxis component being the imaginary part of the vector (i.e. d-q axes are mutually perpendicular, as already emphasised). ...

As far as the AC machines are concerned, simple speed control systems are not capable of providing decoupled (independent) flux and torque control. All the so called scalar speed control methods (constant volts/hertz control, slip frequency control, voltage control etc.) are able of controlling the steady-state behaviour of the machine only.
