Ladder Logic Tutorial with Ladder Logic Symbols &

Ladder logic was designed to have the same look and feel as electrical ladder diagrams, but with ladder logic, the physical contacts and coils are replaced with memory bits. Let's take a look. For this program, the relay logic's ladder diagram is duplicated with ladder logic; no more hard-wired logic, but memory locations instead.

2012-7-3 · The details of the other control loops in Figures 1.5 and 1.7 are left to problems at the end of this chapter. It is worth mentioning that in virtually all cases of process control in chemical processes, the final control element is a valve. Thus, all control logic is based on the effect that a change in a given flowrate has on a given variable....

Application of time series analysis and modern control

Cement plant process is full of internal noise sources and feedback loops. Therefore, statistical approach is required to understand its dynamic characteristics. Time series analysis has been applied to some important subprocesses of a cement plant process. These are the vertical mill process, calcining process and clinker cooling process.

Costec Systems advanced control services. It is generally agreed that less than 80% of modulating control loops are satisfactorily handled by conventional PID controllers even if well-tuned. The remainder are not well-managed by conventional controllers and may be responsive to some form of model-based advanced (modern) control....

As an employee of a small, privately owned industrial services firm, I handled many roles day to day and usually simultaneously. Generally most of my effort was in supporting the fabricators and tradesman of the shop, interfacing with customers, estimating and quoting new projects, ordering materials and CAD based electrical/mechanical design.

 · PID loops are notoriously difficult to tune. Your issues could have nothing to do with the pot and everything to do with the P, I, and D parameters. Not possible to know without trying to duplicate your exact setup. How unlinear is the pot? If it is just a few percent, then that can't account for your PID issues....
