• ### Asymmetrically Modulated AC Chopper

Publication Year: 1982, Page(s):181 - 185
Cited by:  Papers (29)
| | PDF (2250 KB)

The paper describes a current impulse-commutated ac triac chopper employed to obtain the optimum supply power factor correction for reactive loads. The resultant displacement and distortion factors of the supply and efficiency of the load are considered. Theoretical results are in excellent agreement with results obtained experimentally.

A simple multiple pulsewidth modulated (MPWM) ac chopper using power transistors for 3-β power control is discussed. 120° chopping period is used for main transistors so that the circuit can accommodate resistive and lagging or leading power factor loads. Only 1-β sensing is used for 3-β control. An alternate economical power and control schemes for 3-β MPWM ac... View full abstract»

• ### A Microprocessor-Based Time Optimal Control of A Variable-Reluctance Step Motor

Publication Year: 1982, Page(s):190 - 196
Cited by:  Papers (4)  |  Patents (2)
| | PDF (1533 KB)

A time optimal control of a single-stack variable-reluctance step motor by a microprocessor is described. To execute a random move length in minimum or quasi-minimum time in open-loop control, the microprocessor controls the motor velocity by referring and, if necessary, connecting the precalculated and stored acceleration and deceleration tables. This control scheme causes, however, a poor settli... View full abstract»

Publication Year: 1982, Page(s):197 - 201
Cited by:  Papers (3)
| | PDF (1088 KB)

The paper proposes a microprocessor-based unit for online identification of the parameters in linear continuous lumped dynamical systems. The unit implements an algorithm which uses the so-called Poisson mement functionals (PMF) of input-output data from the actual process under identification. View full abstract»

An Alternating Sequential/Parallel'' system, the Mopps was introduced a few years ago and is modified despite the fact that it solved satisfactorily a number of real-time problems. The new system, the Topps'' is described and compared to Mopps in Section II and two applications are chosen to prove it to be superior. In Section III, the advantage of having a third basic, the ring'' mode, is i... View full abstract»

• ### Microcomputer Control of PWM Inverters

Publication Year: 1982, Page(s):212 - 216
Cited by:  Papers (12)
| | PDF (1062 KB)

A method is proposed for implementing on a microcomputer the control of inverters modulated with a digital technique. It consists of storing in the microcomputer memory the switching patterns relative to a limited number of levels of the first harmonics of the inverter output voltage and of computing on line the actual pattern by interpolating the stored values. This allows the inverter output vol... View full abstract»

• ### Digital Simulation Algorithms Using Parallel Processing

Publication Year: 1982, Page(s):217 - 219
Cited by:  Papers (1)
| | PDF (418 KB)

Algorithms are presented which reduce the computation time per integration step compared to the more common methods. This is accomplished by using only algorithms which permit the simultaneous calculation of x and f(x) where x = f(x). These results are important not only in the field of digital simulation, but also in realizing dynamic controllers/estimators digitally, e.g., realizing a nonlinear ... View full abstract»

A control system for a front-end loader linkage is specified and developed. Using a microcomputer, the controller is capable of positioning the linkage in either Cartesian or angular motion with the ability to store and recall trajectories. The hardware and software used in a scale model, and the typical response of the linkage are shown. View full abstract»
