Disturbance Adaptive Discrete-Time Sliding Control With Application to Engine Speed Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a discrete-time adaptive sliding control method for SISO nonlinear systems with a bounded disturbance or unmodeled dynamics. Control and adaptation laws considering input ...
Constant Spacing Strategies for Platooning in Automated Highway Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important aspect of an Automated Highway System is automatic vehicle following. Automatic Vehicle follower systems must address the problem of string stability, i.e., the problem of spacing ...
Pneumatic Actuators for Vehicle Active Suspension Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of actively controlled pneumatic actuators in parallel with conventional passive suspensions to improve vehicle dynamics was investigated. For application on the secondary lateral suspension ...
Automotive Powertrain Modeling for Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic model of an automotive powertrain system is developed by the use of eight states and two time-delays in the continuous-time domain, with careful attention given to the dynamics and ...
A Nonlinear Controller Design Method for Fuel-Injected Automotive Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear, “sliding mode” fuel-injection controller is designed based on a physically motivated, mathematical engine model. The designed controller can achieve a commanded air-to-fuel ratio with ...
Modeling and Validation of Automotive Engines for Control Algorithm Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is considerable interest in coordinated automotive engine/transmission control to smooth shifts, and for traction control of front wheel vehicles. This paper outlines a nonlinear dynamic ...
Estimation of Vehicle Shaft Torque Using Nonlinear Observers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current closed-loop automotive shift control algorithms could greatly benefit if a measurement of the drive axle shaft torque was available. Direct measurements using strain gauges are too expensive ...
Application of Approximate I/O Linearization to Aircraft Flight Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the performance enhancement of a statically unstable aircraft subject to the input and state constraints. Under control saturation, i/o linearizability is destroyed and the ...
Robust Throttle Control of Automotive Engines: Theory and Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An adaptive, sliding control algorithm is developed for automated throttle control of an I.C. engine to be used in drive-by-wire applications such as coordinated engine/transmission gear shiftings, ...
String Instabilities in Formation Flight: Limitations Due to Integral Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flying in formation improves aerodynamic efficiency and, consequently, leads to an energy savings. One strategy for formation control is to follow the preceding vehicle. Many researchers have ...
