   Multi-input Variable Structure Controllers for Electronic Converters
By A. E. van der Groef; P. P. J. van den Bosch; H. R. Visser [View]
[Download]

Abstract: Variable Structure Control (VSC) laws for multi-input systems are studied for controlling electronic converters. Each switch in the converter is considered as an input, so converters with several switches can be dealt with. VSC control laws yield fast responses and a robust behaviour against large parameter variations. To incorporate the effects of the different switches on each other, the hierarchy of control method is used. The proposed control method is applied in designing an appropriate controller for a switching power converter.

   VARIABLE STRUCTURE CONTROL OF A BRUSHLESS MOTOR
By C. Rossi; A. Tonielli; R. Zanasi [View]
[Download]

Abstract: Variable Structure System approach to the control of a brushless motor in the robotic area is considered. A cascaded control structure with separated loops for velocity and current control is used. Two different techniques are used for the design of the two control loops, in order to achieve robustness with respect to variations of electrical and mechanical parameters. The inner current controller has been synthesized using a Sliding Mode approach. For the outer velocity regulator, a Binary Control approach has been adopted, getting robustness to parameter variations without high-frequency chattering. Simulations are presented to show robustness properties of the proposed control scheme.

   EXPERIMENTAL LOW-CHATTERING SLIDING-MODE CONTROL OF A PM MOTOR DRIVE
By A. Consoli; A. Raciti; A. Testa [View]
[Download]

Abstract: In the present paper the chattering reduction problem is faced for a position Sliding-control of a Permanent Magnet (PM) motor drive, in which a sliding trajectory composed of three segments is used to ensure fully Sliding-Mode controlled transients, and a method is proposed to achieve a low chattering with a good robustness by using a combination of an hysteresis Sliding-mode control and an adaptive speed control. An experimental prototype is presented which consists of a current controlled PWM inverter, an interior PM motor, and the Sliding-Mode speed and position control digitally implemented on a DSP.
