There are few of transient control models are adapted to asynchronous induction coil launcher (AICL) with air core coil. Thus, many papers about AICL were written with the goal of increasing muzzle velocity of projectile. This paper concentrate on how to control the projectile speed and thrust accurately by using improved current filament (CF) method and variable voltage variable frequency (VVVF)...
There are many industrial applications where precise delivery of fluid required such as ratio blending, delivery system, etc. One of such application is petroleum product delivery system. As the price of these petroleum products is increasing day by day, it is important to deliver the exact demanded quantity of product to the customer. For such delivery systems the digital control valve is used. This...
This paper focuses on using the Robotics Toolbox in MATLAB for simulating the motion and environmental physics of a two-legged humanoid robot. The said software is built primarily for single serial-link manipulators in a free environment without holonomic constraints. Methods for additional functionality required for a biped interacting with an environment and control schemes for simulation are presented...
In this paper, linear elevator driven by permanent magnet synchronous linear motor (PMLSM) is used in fuzzy PID control method, in which it is to adopt the magnetic guidance system to control the PMLSM gap which changed frequently, and it can impact the vertical thrust and control the level vibration and noise in the process of start, operation, and stop to make passenger comfortable. Matlab modeling...
This paper focused on modeling and performance analysis of linear inverted pendulum and design and simulation of LQR controller. Main to introduce how to built the mathematic model and the analysis of it's system performance, then design a LQR controller in order to get the much better control. Simulation is done to show the efficiency and feasibility of proposed approach.
This paper describes a position control of 2 degrees of freedom (DOF) XY Piezo Actuator Stage (XY PAS) with Feedforward Neural Network (FNN) and additional Particle Swarm Optimization (PSO) approach, which is used as an improved learning method for optimizing the weights of FNN rather than just the standard technique of back-propagation of errors.
This paper presents a novel and practical approach for integrating simulation and optimization of system dynamics (SD) models using Matlab and Simulink. The Matlab platform allows much freedom in customizing and implementing global search techniques such as genetic algorithms (GA) and artificial intelligence constructs like fuzzy logic. The Simulink platform allows complex nonlinear dynamic models...
Quantification of the lumbar spine compression and shear forces is a continuing challenge in biomechanics. The purpose of this study is to develop a virtual model with the ability to determine the kinetics of lumbar spine joints during complex activities.
The development of advanced vehicle control systems such as ABS, TCS and ESP, depend upon the information about tire-road force, which can not be measured directly in modern cars. A model-based estimation methodology of the tire-road force using a sliding model observer is proposed in this paper. Hyperbolic tangent function is chosen to cover chattering effects of observer. A simulation platform which...
In order to improve the mechanical behavior of mast link frame system of rotary drilling rig, studying on the impact of installation angle of mast link frame system is necessary. Based on Newton-Euler method, the kinematic and dynamic constraint equations of mast link frame system were derived. The dynamic simulation model based on MATLAB was built in Simulink, and a series of simulation were run...
Pneumatic muscles mimic function of human muscles and are used as robot actuators. The intelligent pneumatic muscle (IPM) with shape memory alloy (SMA) wires braided shell was proposed to improve characteristics. The mechanism was designed and prototype test-bench was made. Output force model was established through static force equilibrium analysis. The equation between temperature and contraction...
The vibration originated from the rotor's unbalance mass impacts on the current oscillation. As the rotor rotating at high speed, Power amplifier circuit will be burned down by excessive control current. While vibrating force transfers to frame, which causes the system vibration and influence the dynamic properties and safe operation. So unbalance compensation on the rotating machine is necessary,...
