Using a loop compensation tool, one solution would be to decrease the gain until the output impedance appeared constant, or until the current spikes had gone (Figure 4). In this case example, with ...

In motion control applications, you frequently hear all sorts of loops -- open, closed, current, torque, speed, voltage, and so on. Here, we define and explain these terms.

Different programmable logic controllers (PLCs) handle PID control loops in different ways. Some loops need to be set manually, while others can use an autotune process embedded in the PLC's software.

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but ...

The non-invasive stability assessment, whether performed as a physical test or with a circuit simulation, is a fast, simple, and inexpensive means to verify or optimize any control loop design. This ...

Maxim’s MAX9930-MAX9933 low-power logarithmic amplifiers are available with three different voltage input ranges, eliminating the need for external attenuators. The MAX9930-MAX9933 low-cost, low ...

According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Control valve selection plays a ...

The four closed-loop poles using PID control plus a second derivative gain (two poles overlap) can be moved to the left to avoid oscillations and increase the operating frequency of the system.

Designing a closed-loop, controlled power supply or motor-control system presents two main challenges. First, the design requires sending feedback voltage or current information across an ...
