Question

In optimum time switching curve the system takes :

(a) Minimum time in reaching desired location

(b) Maximum time in reaching desired location

(c) Never reaches

(d) No desired location is present

I got this question at a job interview.

I'd like to ask this question from Construction of Phase-Trajectories topic in division Nonlinear Systems of Control Systems

Answer 1

Correct answer is (a) Minimum time in reaching desired location

Best explanation: If switching is made to occur the crossing of the starting trajectory with the thick line trajectory the system follows the trajectory and reaches the desired output at the minimum time.
