Abstract

This paper illustrates the operation of a tubular-machine drive as a linear generator for a heave-buoy wave energy conversion. Linear generators, which are adopted in marine power plants, offer the advantage of generating without introducing any conversion crank gear or hydraulic system. The use of a tubular-machine topology allows the electromagnetic thrust density to be improved. This paper briefly summarizes the principles of marine wave buoy interaction and reports the design analysis and control of a permanent-magnet (PM) synchronous tubular linear machine based on a scaled generator prototype and on a rotating simulation test bench. Index Terms--Heave buoy, linear synchronous generators, marine energy, tubular generators.

Abstract

The traction control is a tool to increase stability and safety and it has a greater performance potential in electrical vehicles (EVs) than in internal combustions vehicles. Moreover, the traction control allows the EV to operate more efficiently preventing slippage in acceleration and permitting the use of use high-efficiency low-drag tires. The presented approach can compete with the well-recognized techniques, but it offers a lighter tuning procedure. This paper presents an approach to the longitudinal control of a single wheel adopting a configuration based on an adherence estimator and a controller of the adherence gradient. Two adherence gradient controllers are examined in the paper: a fuzzy controller and a sliding mode controller. In both cases, the presented approach allows for tracking a value of the adherence derivative in a wide operating range without any knowledge of the road conditions. The work is based on numerical simulations as well as experimental tests. The test bench computes in real-time the vehicle dynamic and loads accordingly, the drive under test. Both controllers were experimentally verified showing good behavior and good response to a sudden change in the road characteristics, whereas the best overall performance was recorded with the sliding mode control. Index Terms--Electric vehicle (EV).

29. A STOCHASTIC CONTROLLER FOR ANTI-SKIDDING MICROPROCESSOR SYSTEM

Abstract

The paper deals with the analysis of an original anti-skid controller suitable for electrical traction drive when the qualification of automatical steering imposes strict rules about the time running, target braking and vehicle stability and handling. The presented controller includes anti-skid braking and anti-spin acceleration functions. After an analytical discussion about mathematical modelling and identification of wheel-road conditions by means of an original stochastic modellization, a stochastic input controller schema is proposed. The main feature of such a controller is the overcoming of a deterministic point of view of standard anti slip systems. Furthermore the strategy control is oriented to a maximization of traction effort in no-adherence conditions too.
