This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Extrusion Process: Taping Process: Line speed and distance between actuators and sensors change Constraints: for instance: tape tension range, Capacitance range IO setpoints: Cap target, more inputs to provide input targets Disturbance: tape spool edge thickness variation.
Control moves from k to m-1, m is control horizon. Output setpoint tracking: force the plant outputs to follow their setpoints Input setpoint tracking: force the plant inputs to follow their setpoints for plants with more inputs than outputs, the inputs are not unique unless defining some inputs as their setpoints to follow. The setpoints usually represent operating conditions that improve safety, economic return, etc. Control move suppression: the controller’s setpoint tracking degrade; less sensitive to prediction inaccuracies (more robust)
Control horizon nc: Predictive horizon: Why the controller bothers to optimize over P future sampling periods and calculate M future moves when it discards all but the first move in each cycle? Constraints: given sufficiently long horizons, the controller can “see” a potential constraint and avoid it or at least minimize its adverse effects. Plant delays: suppose that the plant includes a pure time delay equivalent to D sampling instants. In other words, the controller’s current move, uk, has no effect until yk_D_1. In this situation it is essential that P>>D and M<<P-D, as this forces the controller to consider the full effect of each move. Non-minimum phase plants: consider a SISO plant with an inverse-response, i.e., a plant with a short-term response in one direction, but a longer term response in the opposite direction. The optimization should focus primarily on the longer term behavior. Otherwise, the controller would move in the wrong direction. Rules of thumb: Choose the control interval such that the plant’s open-loop setting time is about 20 to 30 sampling periods (i.e., the sampling period is approximately one fifth of the dominant time constant). Choose prediction horizon P to be the number of sampling periods used in step 1. Use a relative small control horizon M e.g., 3-5

MPC design with input and output constraints, time delay and models MPC implementation Control action outputs
Define np and nu Define input and output setpoint profile Give to MPC implementation VI
Taping application Manual mode to show the disturbance and normal operating condition Auto mode to set setpoint following and disturbance rejection. Output weight on impedance, let OD free. Histogram and real-time trending charts Z and FOD Output constraints. Alarm to stop machine and quality tracking
Use Matlab m script server with LabVIEW Same way to design MPC
MPC m script node with code in it
MPC implementation Manual to show the disturbance and operating condition Auto to show setpoint following and disturbance rejection Weighting factor the same. Point out the issues on this approach - Matlab software required - simulate in Matlab and in Labview, and then implement in Labview - software upgrades to make sure the interface works between Matlab and Labview - Tech support not as good
Extrusion process graph explanation Time delay mode but control OD automatically. Point to the label printing and spool quality checking, alarm tracking, etc Screw speed and line speed feedforward compensation to increase productivity
Output weighting Original OD weighting higher, and then Z weighting higher to see the setpoint following effects based on the weight tuning parameters. Feedforward compensation, spool summary, and quality label for test reduction
Company product win third party test result for consistent quality. Taping line setup eliminate night shift Feedforward line speed/screw speed ramp up Laser gauge elimination due to multivariable MPC controller. For instance, dielectric OD laser malfunction, operator did not see it, but the controller acted up, therefore detect sensor fault On-line quality tracking and prediction, reduced off-line coax test.
