PID Controller Tuning (Ziegler-Nichols)
Calculate PID controller parameters using the Ziegler-Nichols open-loop method (step response) for i…
Kp = 1.2/a Ti = 2×Tu Td = 0.5×Tu where a = K×Tu/T (from step test)
Encoder Resolution & Positioning Accuracy
Calculate positioning accuracy, speed measurement resolution and distance per pulse for rotary and l…
Resolution = (360° / PPR × gear_ratio) | Linear: distance_per_pulse = pitch / (PPR × 4)
Fieldbus Cycle Time & Bandwidth
Estimate the cycle time and available bandwidth for common industrial fieldbus and industrial Ethern…
T_cycle = T_frame × N_nodes + T_overhead | Bandwidth_used = (payload × N) / T_cycle
Servo Motor & Drive Sizing
Calculate required servo motor torque and power for a positioning application, including acceleratio…
T_accel = J_total × α | T_total = T_accel + T_friction + T_gravity | T_rms = √(ΣT²×t / t_cycle)
PLC I/O Estimation & Hardware Planning
Estimate total PLC I/O count and rack/module requirements from a list of field devices and actuators…
I/O modules = ⌈ (Total I/O × 1.15) / Points_per_module ⌉
