It is a strictly causal negative controller with a zero and 2 poles, which generates a complete control system T(z) stable, perfectly precise to step, but slow, with some oscillations and overshoot

I was not able to find any controller that made my complete control system T(z) stable

It is a strictly causal lead controller, which generates a complete control system T(z) stable, precise enough to step and with both enough speed and oscillations and overshoot small enough

It is a strictly causal negative PIDz (discrete proportional integral and derivative controller) plus a double lag, which generates a complete control system T(z) stable, precise enough to step and with both enough speed and oscillations and overshoot small enough

It is a strictly causal negative PIDz (discrete proportional integral and derivative controller), which generates a complete control system T(z) stable, perfectly precise to step, but slow and with some oscillations and overshoot

It is a strictly causal negative proportional controller, which generates a complete control system T(z) stable, precise enough to step and with both enough speed and both oscillations and overshoot small enough

It is a strictly causal positive PIDz (discrete proportional integral and derivative controller), which generates a complete control system T(z) stable, with bad precision to step but without oscillations, only small overshoot and very fast

It is a strictly causal negative proportional controller, which generates a complete control system T(z) stable, with reasonable precision to step and with important oscillations, small overshoot and fast enough

It is a strictly causal lag controller, which generates a complete control system T(z) stable, with reasonable precision to step and with important oscillations, small overshoot and fast enough

It is a strictly causal positive proportional controller, which generates a complete control system T(z) stable, precise enough to step and with both enough speed and both oscillations and overshoot small enough

It is a strictly causal positive proportional controller, which generates a complete control system T(z) stable, with reasonable precision to step and with important oscillations, small overshoot and fast enough

It is a strictly causal dead-beat controller, which generates a complete control system T(z) stable, with perfect precision to step, without oscillations and very fast (but a big a gain)
