“…19 Since PMDC motors cannot produce a sufficiently high torque, a two-stage gear train exists between the motor and the output shaft. The second actuator is a torquemotor-based single-action rotary actuator, 20 which is used to regulate the charge air temperature by the air coming directly from the turbocharger with cooled air from a heat exchanger. The torque motor produces a sufficiently high torque and can drive the actuator directly, without additional gearing.…”

This paper presents a synthesis of non-linearities present in mechatronic air path actuators of diesel engines. These actuators allow precise control over air path dynamics because of their fast response times and accuracy in transient conditions. However, the non-linearities present in their characteristics limit their closed-loop performance. In this paper we discuss various non-linear phenomena existing in actuator characteristics and their physical causes. Different modelling schemes for the physical causes are also presented, which simulate the non-linear behaviour of the actuators. Furthermore, other factors, such as operational conditions and ageing, and their degrading effects on the actuator performance, are also discussed.

“…This task will be accomplished by applying discontinuous control on 'v' using the three algorithms presented in the last section. The actuator physical parameters have been experimentally found out using the methods given in [5,11,30], the values are given in table 1. Detailed discussion on finding bounding constants and controller parameters has been presented in [29].…”

This paper presents experimental results of practical implementation of three higher -order sliding-mode control algorithms. The considered algorithms are applied to the position control of an engine air path mechatronic actuator. This actuator is used to control the swirl air entering the cylinders of a diesel engine. Three output-feedback second order sliding-mode controllers have been designed and tested on the actuator. The most effective strategies have been tested for robustness in varying temperature and load conditions. The experimental results show the effectiveness and robustness of the control techniques.

This paper present a new design of a Limited angle torque motor (LATM) with Dual Halbach Arrays for rotary direct drive valve (DDV), which needs high frequency response, high power to weight ratio. Reluctance model of proposed LATM is discussed. The structure parameters are optimized by particle swarm optimization (PSO) method to improve performances, especially the output torque. The optimized parameters are validated by the FEM method. It is shown that the new design improves the output torque significantly.
