On descent into ZZZ; we smelled a strong acrid smell like something was burning.  We notified ATC and requested direct the field.  We were given direct to the IAF.  I went as fast as I could before the smell got worse or we started to get smoke in the cockpit.  We continued the approach and landed uneventfully. [Unknown]System malfunction.
