Design Automation Systems with a Focus on Diagnostics and Situational Awareness

My first post regarding good automation system design concepts approached the issue of robust design from the field level, looking at field devices and wiring practices. This time we move up the automation food chain to look at the control platform, which is made up of controllers, input/output (I/O) modules, and the networking means that […]

Fuzzy Model Based Adaptive PID Controller Design for Nonlinear and Uncertain Processes

Abstract: We develop a novel adaptive tuning method for classical proportional–integral–derivative (PID) controller to control nonlinear processes to adjust PID gains, a problem which is very difficult to overcome in the classical PID controllers. By incorporating classical PID control, which is well-known in industry, to the control of nonlinear processes, we introduce a method which can […]

Is There Enough Focus on Cybersecurity for Municipal Infrastructure?

The volumes of information written about cybersecurity can be mind-boggling. The subject has important implications for everyone, especially for those of us involved with industrial control systems and software-based automation of water, sewer and electric systems. Legacy control systems have always been vulnerable because they weren’t designed with cyber attacks in mind. They were designed […]
