This paper investigates the methodology to develop low-order nonlinear state space models for flow response along the centerline of a very aggressive (length to exit diameter ratio, L/D, of 1.5) inlet duct. Reduced order models are constructed by using Numerical Algorithms for State Space Subspace System Identification (N4SID), based on 2D numerical flow simulation data. The identified models successfully...
This paper describes a modeling and control approach for the thermal aspects of a high-temperature semiconductor crystal growth process. From a thermal perspective, each crystal growth cycle is composed of three distinct phases, heat up, growth, and cool down, each with specific control challenges and objectives. This paper focuses on the heat up and growth phases. A simulation model is first developed...
This paper describes the algorithm development and experimental results of a multi-probe micro-assembly system. The experimental testbed consists of two actuated probes, an actuated die stage, and vision feedback. The kinematics relationships for the probes, die stage, and part manipulation are derived and used for calibration and kinematics-based planning and control. Particular attention has been...
